   &lt;p style="margin-top:12px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Note 1. Summary of Significant Accounting Policies &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Principles of Consolidation and Basis of Presentation &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The accompanying unaudited condensed consolidated financial statements include those of Cerus Corporation and its subsidiary, Cerus Europe
   B.V. (collectively referred to hereinafter as &amp;#8220;Cerus&amp;#8221; or the &amp;#8220;Company&amp;#8221;) after elimination of all intercompany accounts and transactions. These condensed consolidated financial statements have been prepared in accordance with
   accounting principles generally accepted in the United States of America (&amp;#8220;GAAP&amp;#8221;) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (&amp;#8220;SEC&amp;#8221;). Accordingly, they do
   not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring entries, considered necessary for a fair presentation have been made.
   Operating results for the three and nine months ended September&amp;#160;30, 2012, are not necessarily indicative of the results that may be expected for the year ending December&amp;#160;31, 2012, or for any future periods. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;As previously reported in Note 20, Quarterly Financial Information, in the Notes to Consolidated Financial Statements included in the
   Company&amp;#8217;s 2011 Annual Report on Form 10-K for the year ended December&amp;#160;31, 2011, filed with the SEC on March&amp;#160;5, 2012, the Company restated previously reported financial statements for the three and nine months ended September&amp;#160;30,
   2011. The adjustments related to previously capitalized inventory costs, which should have been charged to cost of product revenue as products were sold. Although the correction was immaterial to the three and nine months ended September&amp;#160;30,
   2011, the Company decided to restate the amounts previously reported to better reflect the actual operating trends of the Company&amp;#8217;s business for 2011. The adjustments primarily increased cost of product revenue by $0.1 million and $0.3 million
   for the three and nine months ended September&amp;#160;30, 2011, respectively. The offsetting adjustment entry was a reduction to the carrying value of inventory. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   These condensed consolidated financial statements and notes thereto should be read in conjunction with the Company&amp;#8217;s audited financial statements and notes thereto for the year ended
   December&amp;#160;31, 2011, which were included in the Company&amp;#8217;s 2011 Annual Report on Form 10-K, filed with the SEC on March&amp;#160;5, 2012. The accompanying balance sheet as of December&amp;#160;31, 2011, has been derived from the Company&amp;#8217;s
   audited financial statements as of that date. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Use of Estimates &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The preparation of financial statements requires management to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related
   disclosures of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates, which are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual
   results may differ from those estimates under different assumptions or conditions. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Revenue &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company recognizes revenue in accordance with ASC Topic 605-25, &lt;i&gt;&amp;#8220;Revenue Recognition &amp;#8211; Arrangements with Multiple
   Deliverables,&amp;#8221;&lt;/i&gt; as applicable. Revenue is recognized when (i)&amp;#160;persuasive evidence of an agreement with the funding party exists; (ii)&amp;#160;services have been rendered or product has been delivered; (iii)&amp;#160;pricing is fixed or
   determinable; and (iv)&amp;#160;collection is reasonably assured. The Company&amp;#8217;s main sources of revenues for the three and nine months ended September&amp;#160;30, 2012, and 2011, were product revenue from sales of the INTERCEPT Blood System for
   platelets and plasma (&amp;#8220;platelet and plasma systems&amp;#8221;) and United States government grants and awards. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Revenue
   related to product sales is generally recognized when the Company fulfills its obligations for each element of an agreement. For all sales of the Company&amp;#8217;s INTERCEPT Blood System products, the Company uses a binding purchase order and signed
   sales contract as evidence of a written agreement. The Company sells its platelet and plasma systems directly to blood banks, hospitals, universities, government agencies, as well as to distributors in certain regions. Generally, the Company&amp;#8217;s
   contracts with its customers do not provide for open return rights, except within a reasonable time after receipt of goods in the case of defective or non-conforming product. Deliverables and the units of accounting vary according to the provisions
   of each purchase order or sales contract. For revenue arrangements with multiple elements, the Company determines whether the delivered elements meet the criteria as separate units of accounting. Such criteria require that the deliverable have
   stand-alone value to the customer and that if a general right of return exists relative to the delivered item, delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. Once the
   Company determines if the deliverable meets the criteria for a separate unit of accounting, the Company must determine how the consideration should be allocated between the deliverables and how the separate units of accounting should be recognized
   as revenue. Consideration received is allocated to elements that are identified as discrete units of accounting based on the best estimated selling price. The Company has determined that vendor specific objective evidence is not discernible due to the Company&amp;#8217;s limited history of selling its products and variability in
   its pricing across the regions into which it sells its products. Since the Company&amp;#8217;s products are novel and unique and are not sold by others, third-party evidence of selling price is unavailable. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;At September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the Company had $0.7
   million and $0.1 million, respectively, of short-term deferred revenue on its condensed consolidated balance sheets related to future performance obligations. Freight costs charged to customers are recorded as a component of revenue under ASC Topic
   605, &lt;i&gt;&amp;#8220;Accounting for Shipping and Handling Fees and Costs.&amp;#8221;&lt;/i&gt; Value-added-taxes (&amp;#8220;VAT&amp;#8221;) that the Company invoices to its customers and remits to governments are recorded on a net basis, which excludes such VAT from product
   revenue. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Revenue related to the cost reimbursement provisions under
   development contracts or United States government grants is recognized as the costs on the projects are incurred. The Company has received certain United States government grants and contracts that support research in defined research projects.
   These grants generally have provided for reimbursement of approved costs incurred as defined in the various grants. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Research and Development Expenses &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In accordance with ASC Topic 730, &lt;i&gt;&amp;#8220;Accounting for Research and Development Expenses,&amp;#8221;&lt;/i&gt; research and development expenses
   are charged to expense when incurred, including cost incurred under each grant that has been awarded to the Company by the United States government or development contracts. Research and development expenses include salaries and related expenses for
   scientific personnel, payments to consultants, supplies and chemicals used in in-house laboratories, costs of research and development facilities, depreciation of equipment and external contract research expenses, including clinical trials,
   preclinical safety studies, other laboratory studies, process development and product manufacturing for research use. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The
   Company&amp;#8217;s use of estimates in recording accrued liabilities for research and development activities (see &amp;#8220;Use of Estimates&amp;#8221; above) affects the amounts of research and development expenses recorded and revenue recorded from development
   funding and government grants and collaborative agreements. Actual results may differ from those estimates under different assumptions or conditions. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Cash Equivalents &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company considers all highly liquid investments with original maturities of three months or less from the date of purchase to be classified as cash equivalents. These investments primarily consist of
   money market instruments, and are classified as available-for-sale. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Short-Term Investments &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Investments with original maturities of greater than three months but less than one year from the date of purchase as well as
   available-for-sale investments with original maturities of greater than one year from the date of purchase, which included United States government agency securities, are classified as short-term investments. In accordance with ASC Topic 320,
   &lt;i&gt;&amp;#8220;Accounting for Certain Investments in Debt and Equity Securities,&amp;#8221;&lt;/i&gt; the Company has classified all debt securities as available-for-sale at the time of purchase and reevaluates such designation as of each balance sheet date.
   Available-for-sale securities are carried at estimated fair value. Unrealized gains and losses derived by changes in the estimated fair value of available-for-sale securities are recorded in &amp;#8220;Accumulated other comprehensive income&amp;#8221; on the
   Company&amp;#8217;s condensed consolidated balance sheets and/or in &amp;#8220;Net unrealized losses on available-for-sale securities, net of taxes&amp;#8221; on the Company&amp;#8217;s condensed consolidated statements of comprehensive income (loss). Realized gains
   and losses from the sale or maturity of available-for-sale investments are recorded in &amp;#8220;Other income (expense), net&amp;#8221; on the Company&amp;#8217;s condensed consolidated statements of operations. The cost of securities sold is based on the
   specific identification method. The Company reports the amortization of any premium and accretion of any discount resulting from the purchase of debt securities as a component of interest expense. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company also reviews all of its marketable securities on a regular basis to evaluate whether any security has experienced an
   other-than-temporary decline in fair value. Other-than-temporary declines in market value are recorded in &amp;#8220;Other income (expense), net&amp;#8221; on the Company&amp;#8217;s condensed consolidated statements of operations. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Restricted Cash &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company holds a certificate of deposit with a domestic bank for any potential decommissioning resulting from the Company&amp;#8217;s
   possession of radioactive material. The certificate of deposit is held to satisfy the financial surety requirements of the California Department of Health Services and is recorded in &amp;#8220;Restricted cash&amp;#8221; on the Company&amp;#8217;s condensed
   consolidated balance sheets. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="font-size:1px;margin-top:18px;margin-bottom:0px"&gt;&amp;#160;&lt;/p&gt;
   &lt;p style="margin-top:0px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Concentration of Credit Risk &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents,
   short-term investments and accounts receivable. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Pursuant to the Company&amp;#8217;s investment policy, substantially all of the
   Company&amp;#8217;s cash, cash equivalents and short-term investments are maintained at a major financial institution of high credit standing. The Company monitors the financial credit worthiness of the issuers of its investments and limits the
   concentration in individual securities and types of investments that exist within its investment portfolio. Generally, all of the Company&amp;#8217;s investments carry high credit quality ratings, which is in accordance with its investment policy. At
   September&amp;#160;30, 2012, the Company does not believe there is significant financial risk from non-performance by the issuers of the Company&amp;#8217;s cash equivalents. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   Concentrations of credit risk with respect to trade receivables exist. However, in connection with the Company&amp;#8217;s revolving line of credit, as discussed in Note 8 in the Notes to Condensed
   Consolidated Financial Statements, the Company purchased a credit insurance policy that mitigates some of its credit risk, as the policy will pay either the Company or its lender on eligible claims filed on its outstanding receivables. On a regular
   basis, including at the time of sale, the Company performs credit evaluations of its customers. Generally, the Company does not require collateral from its customers to secure accounts receivable. To the extent that the Company determines specific
   invoices or customer accounts may be uncollectible, the Company reserves against the accounts receivable on its condensed consolidated balance sheets and records a charge on its condensed consolidated statements of operations. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company had three customers and two customers that accounted for more than 10% of the Company&amp;#8217;s outstanding trade receivables at
   September&amp;#160;30, 2012, and December&amp;#160;31, 2011, respectively. These customers cumulatively represented approximately 69% and 58% of the Company&amp;#8217;s outstanding trade receivables at September&amp;#160;30, 2012, and December&amp;#160;31, 2011,
   respectively. To date, the Company has not experienced collection difficulties from these customers. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Inventories &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   At September&amp;#160;30, 2012, and December&amp;#160;31, 2011, inventory consisted of work-in-process and finished goods only. Finished goods include INTERCEPT disposable kits, UVA illumination devices
   (&amp;#8220;illuminators&amp;#8221;), and certain replacement parts for the illuminators. Platelet and plasma systems&amp;#8217; disposable kits generally have a two-year life from the date of manufacture. Illuminators and replacement parts do not have regulated
   expiration dates. Work-in-process includes certain components that are manufactured over a protracted length of time, which can exceed one year, before being incorporated and assembled by Fenwal, Inc. (&amp;#8220;Fenwal&amp;#8221;) into the finished INTERCEPT
   disposable kits. The Company maintains an inventory balance based on its current sales projections, and at each reporting period, the Company evaluates whether its work-in-process inventory would be consumed for production of finished units in order
   to sell to existing and prospective customers within the next twelve-month period. It is not customary for the Company&amp;#8217;s production cycle for inventory to exceed twelve months. Instead, the Company uses its best judgment to factor in lead times
   for the production of its finished units to meet the Company&amp;#8217;s current demands. If actual results differ from those estimates, work-in-process inventory could potentially accumulate for periods exceeding one year. At September&amp;#160;30, 2012,
   and December&amp;#160;31, 2011, the Company classified its work-in-process inventory as a current asset on its condensed consolidated balance sheets based on its evaluation that the work-in-process inventory would be consumed for production and
   subsequently sold within each respective subsequent twelve-month period. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Inventory is recorded at the lower of cost,
   determined on a first-in, first-out basis, or market value. The Company uses significant judgment to analyze and determine if the composition of its inventory is obsolete, slow-moving or unsalable and frequently reviews such determinations. The
   Company&amp;#8217;s limited history selling the INTERCEPT Blood System limits the amount of historical data the Company has to perform this analysis. Generally, the Company writes-down specifically identified unusable, obsolete, slow-moving, or known
   unsalable inventory that has no alternative use in the period that it is first recognized by using a number of factors including product expiration dates, open and unfulfilled orders, and sales forecasts. Any write-down of its inventory to net
   realizable value establishes a new cost basis and will be maintained even if certain circumstances suggest that the inventory is recoverable in subsequent periods. Costs associated with the write-down of inventory are recorded in &amp;#8220;Cost of
   product revenue&amp;#8221; on the Company&amp;#8217;s condensed consolidated statements of operations. At September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the Company had $0.3 million and $0.6 million, respectively, reserved for potential obsolete,
   expiring or unsalable product. At September&amp;#160;30, 2012, the Company also wrote-down the value of certain unsaleable inventory of $1.1 million for which the Company has an offsetting warranty claim against Fenwal. See below in Note 1 in the Notes
   to Condensed Consolidated Financial Statements under &amp;#8220;Guarantee and Indemnification Arrangements&amp;#8221; and Note 12 in the Notes to Condensed Consolidated Financial Statements for further information regarding the Company&amp;#8217;s warranty claim
   with Fenwal. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Property and Equipment, net &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Property and equipment is comprised of furniture, equipment, information technology hardware and software and is recorded at cost. At the
   time the property and equipment is ready for its intended use, it is depreciated on a straight-line basis over the estimated useful lives of the assets (generally three to five years). Leasehold improvements are amortized on a straight-line basis
   over the shorter of the lease term or the estimated useful lives of the improvements. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="font-size:1px;margin-top:18px;margin-bottom:0px"&gt;&amp;#160;&lt;/p&gt;
   &lt;p style="margin-top:0px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Goodwill and Intangible Assets, net &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Additions to goodwill and intangible assets, net are derived at the time of a business acquisition, in which the Company assigns the total
   consideration transferred to the acquired assets based on each asset&amp;#8217;s fair value and any residual amount becomes goodwill, an indefinite life intangible asset. Intangible assets, net, which include a license for the right to commercialize the
   INTERCEPT Blood System in Asia, are subject to ratable amortization over the estimated useful life of ten years. The amortization of the Company&amp;#8217;s intangible assets, net, is recorded in &amp;#8220;Amortization of intangible assets&amp;#8221; on the
   Company&amp;#8217;s condensed consolidated statements of operations. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Goodwill is not amortized but instead is subject to an
   impairment test performed on an annual basis, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Such impairment analysis is performed on August&amp;#160;31 of each fiscal year, or more frequently if
   indicators of impairment exist. Effective January&amp;#160;1, 2012, the test for goodwill impairment may be assessed using qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the
   carrying amount. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than the carrying amount, the Company must then proceed with performing the quantitative two-step process to test goodwill for
   impairment; otherwise, goodwill is not considered impaired and no further testing is warranted. The Company may choose not to perform the qualitative assessment to test goodwill for impairment and proceed directly to the quantitative two-step
   process; however, the Company may revert to the qualitative assessment to test goodwill for impairment in any subsequent period. The first step of the two-step process compares the fair value of each reporting unit with its respective carrying
   amount, including goodwill. The Company has determined that it operates in one reporting unit and estimates the fair value of its one reporting unit using the enterprise approach under which it considers the quoted market capitalization of the
   Company as reported on the Nasdaq Global Market. The Company considers quoted market prices that are available in active markets to be the best evidence of fair value. The Company also considers other factors, which include future forecasted
   results, the economic environment and overall market conditions. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired and, therefore, the second step of the impairment test is
   unnecessary. The second step of the two-step process, which is used to measure the amount of impairment loss, compares the implied fair value of each reporting unit&amp;#8217;s goodwill with the respective carrying amount of that goodwill. If the
   carrying amount of the reporting unit&amp;#8217;s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company performs an impairment test on its intangible assets, in accordance ASC Topic 360-10, &lt;i&gt;&amp;#8220;Property, Plant and Equipment,&amp;#8221;&lt;/i&gt; if certain events or changes in circumstances occur
   which indicate that the carrying amounts of its intangible assets may not be recoverable. If the intangible assets are not recoverable, an impairment loss would be recognized by the Company based on the excess amount of the carrying value of the
   intangible assets over its fair value. For further details regarding the impairment analysis, reference is made to the section below under &amp;#8220;Long-lived Assets.&amp;#8221; Also, see Note 5 in the Notes to Condensed Consolidated Financial Statements
   for further information regarding the Company&amp;#8217;s impairment analysis and the valuation of goodwill and intangible assets, net. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Long-lived Assets &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company evaluates its long-lived assets for impairment by continually monitoring events and changes in circumstances that could
   indicate carrying amounts of its long-lived assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses recoverability by determining whether the carrying value of such assets will be recovered through the
   undiscounted expected future cash flows. If the expected undiscounted future cash flows are less than the carrying amount of these assets, the Company then measures the amount of the impairment loss based on the excess of the carrying amount over
   the fair value of the assets. The Company did not recognize impairment charges related to its long-lived assets during the three and nine months ended September&amp;#160;30, 2012, and 2011. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Foreign Currency Remeasurement &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The functional currency of the Company&amp;#8217;s foreign subsidiary is the United States dollar. Monetary assets and liabilities denominated
   in foreign currencies are remeasured in United States dollars using the exchange rates at the balance sheet date. Non-monetary assets and liabilities denominated in foreign currencies are remeasured in United States dollars using historical exchange
   rates. Revenues and expenses are remeasured using average exchange rates prevailing during the period. Remeasurements are recorded in the Company&amp;#8217;s condensed consolidated statements of operations. The Company recorded foreign currency gains
   (losses) of $0.2 million and less than $(0.1) million during the three months ended September&amp;#160;30, 2012, and 2011, respectively, and $(0.2) million and $0.4 million during the nine months ended September&amp;#160;30, 2012, and 2011, respectively.
   &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:0px;margin-bottom:0px;page-break-before:always"&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Stock-Based Compensation &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company accounts for stock-based compensation in accordance with ASC Topic 718, &lt;i&gt;&amp;#8220;Compensation &amp;#8211; Stock
   Compensation.&amp;#8221;&lt;/i&gt; Stock-based compensation expense is measured at the grant-date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period, which is the vesting period, and is
   adjusted for estimated forfeitures. To the extent that stock options contain performance criteria for vesting, stock-based compensation is recognized once the performance criteria are probable of being achieved. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;For stock-based awards issued to non-employees, the Company follows ASC Topic 505-50, &lt;i&gt;&amp;#8220;Equity Based Payment to
   Non-Employees&amp;#8221;&lt;/i&gt; and considers the measurement date at which the fair value of the stock-based award is measured to be the earlier of (i)&amp;#160;the date at which a commitment for performance by the grantee to earn the equity instrument is reached or (ii)&amp;#160;the date at which the grantee&amp;#8217;s performance is complete. The Company
   recognizes stock-based compensation expense for the fair value of the vested portion of the non-employee stock-based awards in its condensed consolidated statements of operations. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;See Note 11 in the Notes to Condensed Consolidated Financial Statements for further information regarding the Company&amp;#8217;s stock-based
   compensation assumptions and expenses. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Warrant Liability &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   In August 2009, and November 2010, the Company issued warrants to purchase an aggregate of 2.4&amp;#160;million and 3.7&amp;#160;million shares of common stock, respectively. The material terms of the warrants
   were identical under each issuance except for the exercise price, date issued and expiration date. The Company classifies the warrants as a liability on its condensed consolidated balance sheets as the warrants contain certain material terms which
   require the Company (or its successor) to purchase the warrants for cash in an amount equal to the value of the unexercised portion of the warrants (as determined in accordance with the Black-Scholes option pricing model) in connection with certain
   change of control transactions. In addition, the Company may also be required to pay cash to a warrant holder under certain circumstances if the Company is unable to timely deliver the shares acquired upon warrant exercise to such holder.
   &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The fair value of these outstanding warrants is calculated using the binomial-lattice option-pricing model and is adjusted
   accordingly at each reporting period. The binomial-lattice option-pricing model requires that the Company uses significant assumptions and judgment to determine appropriate inputs to the model. Some of the assumptions that the Company relies on
   include the probability of a change of control occurring, the volatility of the Company&amp;#8217;s stock over the life of the warrant and assumptions and inputs used to value the warrants under the Black-Scholes model should a change of control occur.
   &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Changes resulting from the revaluation of warrants to fair value are recorded in &amp;#8220;Revaluation of warrant liability&amp;#8221;
   on the condensed consolidated statements of operations. Upon the exercise or modification to remove the provisions which require the warrants to be treated as a liability, the fair value of the warrants will be reclassified from a liability to
   stockholders&amp;#8217; equity on the Company&amp;#8217;s condensed consolidated balance sheets and no further adjustment to the fair value would be made in subsequent periods. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   See Note 10 in the Notes to Condensed Consolidated Financial Statements for further information regarding the Company&amp;#8217;s valuation of warrant liability. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Income Taxes &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company accounts for income taxes using an asset and liability approach in accordance with ASC Topic 740 &lt;i&gt;&amp;#8220;Accounting for Income Taxes.&amp;#8221;&lt;/i&gt; Under this method, deferred tax assets and
   liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. ASC
   Topic 740 requires derecognition of tax positions that do not have a greater than 50% likelihood of being recognized upon review by a taxing authority having full knowledge of all relevant information. Use of a valuation allowance as described in
   ASC Topic 740 is not an appropriate substitute for the derecognition of a tax position. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in its income tax expense. To date, the Company has not recognized any
   interest and penalties in its condensed consolidated statements of operations, nor has its accrued for or made payments for interest and penalties. The Company continues to carry a full valuation allowance on all of its deferred tax assets. Although
   the Company believes it more likely than not that a taxing authority would agree with its current tax positions, there can be no assurance that the tax positions the Company has taken will be substantiated by a taxing authority if reviewed. The
   Company&amp;#8217;s tax years 2007 through 2011 remain subject to examination by the taxing jurisdictions. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares
   outstanding for the period. Diluted net income (loss) per common share gives effect to all potentially dilutive common shares outstanding for the period. The potentially dilutive securities include stock options, employee stock purchase plan rights,
   warrants and restricted stock units, which are calculated using the treasury stock method, and convertible preferred stock, which is calculated using the if-converted method. Diluted net income (loss) per common share also gives effect to potential
   adjustments to the numerator for changes resulting from the revaluation of warrants to fair value for the period, even if the Company is in a net loss position if the effect would result in more dilution. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Diluted net loss per common share used the same weighted average number of common shares outstanding for the nine months ended
   September&amp;#160;30, 2012, and 2011, as calculated for the basic net loss per common share as the inclusion of any potential dilutive securities would be anti-dilutive. In addition, certain potential dilutive securities were excluded from the dilution
   calculation for the three months ended September&amp;#160;30, 2012, and 2011, as their inclusion would have been anti-dilutive. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;&amp;#160;&lt;/p&gt;
   &lt;p style="margin-top:0px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The following table sets forth the reconciliation of the numerator
   and denominator used in the computation of basic and diluted net income (loss) per common share for the three and nine months ended September&amp;#160;30, 2012, and 2011 (in thousands, except per share amounts): &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company recognizes the fair value for guarantee and indemnification arrangements issued or modified by the Company after
   December&amp;#160;31, 2002. In addition, the Company monitors the conditions that are subject to the guarantees and indemnifications in order to identify if a loss has occurred. If the Company determines it is probable that a loss has occurred, then any
   such estimable loss would be recognized under those guarantees and indemnifications. Some of the agreements that the Company is a party to contain provisions that indemnify the counter party from damages and costs resulting from claims that the
   Company&amp;#8217;s technology infringes the intellectual property rights of a third party or claims that the sale or use of the Company&amp;#8217;s products have caused personal injury or other damage or loss. The Company has not received any such requests
   for indemnification under these provisions and has not been required to make material payments pursuant to these provisions. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company generally provides for a one-year warranty on certain of its INTERCEPT blood-safety products covering defects in materials
   and workmanship. The Company accrues costs associated with warranty obligations when claims become known and are estimable. During the three months ended September&amp;#160;30, 2012, the Company provided for warranty obligations related to replacement
   costs for certain of its products that the Company identified were defective or had the potential of being defective. Prior to this incident, there have been very few warranty costs incurred. As a result, the Company had not accrued for any
   potential future warranty costs at December&amp;#160;31, 2011. In addition, the Company believes that the defective products and those that had the potential of being defective identified during the three months ended September&amp;#160;30, 2012 are
   isolated. Accordingly, the Company has not accrued for any other incremental potential future warranty costs for its products at September&amp;#160;30, 2012. The product warrant liability is recorded in &amp;#8220;Accrued liabilities&amp;#8221; on the
   Company&amp;#8217;s condensed consolidated balance sheets.
   A reconciliation of changes to the beginning and ending balances of the Company&amp;#8217;s product warranty liability, from December&amp;#160;31, 2011, to September&amp;#160;30, 2012, was as follows

   warranty obligations provided for in relation to certain of its products during the three months ended September&amp;#160;30, 2012, the Company filed a warranty claim against Fenwal, which Fenwal accepted. As a result, the Company recorded a current
   asset of $1.7 million on its condensed consolidated balance sheets as of September&amp;#160;30, 2012 representing the full amount of the warranty claim against Fenwal as Fenwal will supply the Company with replacement products or credit notes for those
   products. The Company also wrote-down the value of certain unsalable inventory of $1.1 million related to these products as an offsetting warranty claim against Fenwal. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company applies the provisions of fair value relating to its financial assets and liabilities. The carrying amounts of accounts
   receivables, accounts payable, and other accrued liabilities approximate their fair value due to the relative short-term maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes
   the fair value of its debt approximates their carrying amounts. The Company measures and records certain financial assets and liabilities at fair value on a recurring basis, including its available-for-sale securities and warrant liability. The
   Company classifies instruments within Level 1 if quote prices are available in active markets, which include its money market funds as the maturity of money market funds are relatively short and the carrying amount is a reasonable estimate of fair
   value. The Company classifies instruments in Level 2 if the instruments are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of
   price transparency. These instruments include the Company&amp;#8217;s available-for-sale securities related to United States government agencies. The available-for-sale securities are held by a custodian who obtains investment prices from a third party
   pricing provider that uses standard inputs to models which vary by asset class. The Company classifies instruments in Level 3 if one or more significant inputs or significant value drivers are unobservable, which include its warrant liability. The
   Company assesses any transfers among fair value measurement levels at the end of each reporting period. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;See Note 2 and 10 in

   December&amp;#160;31, 2011, filed with the SEC on March&amp;#160;5, 2012, under Note 2 in the Notes to Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

   During the nine months ended September&amp;#160;30, 2012, the Company did not dispose of or recognize additional goodwill. On August&amp;#160;31, 2012, the Company performed its annual review of goodwill. As
   described in Note 1 above, the Company applied the enterprise approach by reviewing the quoted market capitalization of the Company as reported on the Nasdaq Global Market to calculate the fair value. In addition, the Company considered its future
   forecasted results, the economic environment and overall market conditions. As a result of the Company&amp;#8217;s assessment that its fair value of the reporting unit exceeded its carrying amount, the Company determined that goodwill was not impaired
   during the nine months ended September&amp;#160;30, 2012. Accordingly, at both September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the carrying amount of goodwill was $1.3 million. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company entered into a loan and security agreement on September&amp;#160;30, 2011, as amended effective on December&amp;#160;13, 2011, and June&amp;#160;30, 2012, with Comerica Bank (&amp;#8220;Comerica&amp;#8221;)
   (collectively, the &amp;#8220;Amended Credit Agreement&amp;#8221;). The Amended Credit Agreement provides for an aggregate borrowing of up to $12.0 million, comprised of a growth capital loan of $5.0 million (&amp;#8220;Growth Capital Loan&amp;#8221;) and a formula
   based revolving line of credit (&amp;#8220;RLOC&amp;#8221;) of up to $7.0 million. The Company pledged all current and future assets, excluding its intellectual property and 35% of the Company&amp;#8217;s investment in its subsidiary, Cerus Europe B.V., as
   security for borrowings under the Amended Credit Agreement. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;Growth Capital Loan &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Concurrent with the execution of the original loan and security agreement in September 2011, the Company borrowed $5.0 million under the
   Growth Capital Loan, substantially all of which was used to repay the Company&amp;#8217;s prior debt with Oxford Finance Corporation (&amp;#8220;Oxford&amp;#8221;), with the remainder used for general corporate purposes. The Growth Capital Loan, which matures on
   September&amp;#160;30, 2015, bears a fixed interest rate of 6.37%, with interest&amp;#8211;only payments due for the first twelve months, followed by equal principal and interest payments for the remaining 36 months. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In September 2011, the Company incurred a commitment fee of $40,000 and loan fees of $50,000, which were recorded as a discount to its
   Growth Capital Loan and are being amortized as a component of interest expense using the effective interest method over the term of the Growth Capital Loan (discount was based on an implied interest rate of 7.07%). The Company will also be required
   to make a final payment fee of 1% of the amounts drawn under Growth Capital Loan due on the earlier of (i)&amp;#160;prepayment of the Growth Capital Loan or (ii)&amp;#160;the maturity of the Growth Capital Loan. The final payment fee will be accreted to
   interest expense using the effective interest method over the life of the Growth Capital Loan upon draw. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="font-size:1px;margin-top:18px;margin-bottom:0px"&gt;&amp;#160;&lt;/p&gt;
   &lt;p style="margin-top:0px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;Revolving Line of
   Credit &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Amended Credit Agreement also provides for a RLOC of up to $7.0 million (the &amp;#8220;RLOC Loan Amount&amp;#8221;). The
   amount available under the RLOC is limited to the lesser of (i)&amp;#160;80% of eligible trade receivables or (ii)&amp;#160;the RLOC Loan Amount. At September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the Company had $3.3 million and $2.3 million,
   respectively, outstanding under the RLOC. The Company is required to repay the principal drawn from the RLOC at the end of the RLOC term on June&amp;#160;30, 2014, or earlier if a portion or all of the outstanding RLOC exceeds the amount available under
   the RLOC. The RLOC bears a floating rate based on the lender&amp;#8217;s prime rate plus 1.50%, with interest&amp;#8211;only payments due each month. At both September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the floating rate of the RLOC was at 4.75%. In
   September 2011, the Company incurred a commitment fee of $20,000. Upon amendment of the loan and security agreement in June 2012, the Company incurred another annual commitment fee of $20,000 and received a credit for the unused portion of the
   initial fee. The Company will incur a $20,000 commitment fee at each annual anniversary beginning June&amp;#160;30, 2013. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;Compliance with Covenants &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company is required to maintain compliance with certain customary and routine financial covenants under the Amended Credit Agreement, including maintaining a minimum cash balance of $2.5 million at
   Comerica and achieving minimum revenue levels, which are measured monthly based on a six-month trailing basis and must be at least 75% of the pre-established future projected revenues for the trailing six-month period. Non-compliance with the
   covenants could result in the principal of the note becoming due and payable. As of September&amp;#160;30, 2012, the Company was in compliance with the financial covenants as set forth in the Amended Credit Agreement. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;&lt;u&gt;2010 Growth Capital Facility &lt;/u&gt;&lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   In March 2010, the Company entered into a growth capital facility agreement with Oxford and immediately borrowed and issued a senior secured note for $5.0 million. The note carried a fixed interest rate
   of 12.04%, with interest&amp;#8211;only payments due for the first nine months and then equal principal and interest payments for an additional 30 months. In September 2011, the Company repaid the outstanding balance of the debt owed to Oxford using the
   proceeds received from the Growth Capital Loan as discussed in further detail above. The Company also accelerated and expensed the remaining closing cost and fees of $0.2 million to interest expense during the three and nine months ended
   September&amp;#160;30, 2011. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;Operating Leases &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company leases its office facilities, located in Concord, California and Amersfoort, The Netherlands, and certain equipment under non-cancelable operating leases with initial terms in excess of one
   year that require the Company to pay operating costs, property taxes, insurance and maintenance. The operating leases expire at various dates through 2019, with certain of the leases providing for renewal options, provisions for adjusting future
   lease payments, which is based on the consumer price index and the right to terminate the lease early, which may occur as early as January 2015. The Company&amp;#8217;s leased facilities qualify as operating leases under ASC Topic 840,
   &lt;i&gt;&amp;#8220;Leases&amp;#8221;&lt;/i&gt; and as such, are not included on its condensed consolidated balance sheets. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;Financed Leasehold
   Improvements &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In December 2010, the Company financed $1.1 million of leasehold improvements. The Company pays for the
   financed leasehold improvements as a component of rent and is required to reimburse its landlord over the remaining life of the respective leases. If the Company exercises its right to early terminate the Concord California lease, which may occur as
   early as January 2015, the Company would be required to repay for any remaining portion of the landlord financed leasehold improvements at such time. At September&amp;#160;30, 2012, the Company had an outstanding liability of $0.9 million related to
   these leasehold improvements, of which $0.1 million was reflected in &amp;#8220;Accrued liabilities&amp;#8221; and $0.8 million was reflected in &amp;#8220;Other non-current liabilities&amp;#8221; on the Company&amp;#8217;s condensed consolidated balance sheets. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company is party to agreements with certain providers for certain components of INTERCEPT Blood System which the Company purchases from third party manufacturers and supplies to Fenwal at no cost for
   use in manufacturing finished INTERCEPT disposable kits. Certain of these agreements require minimum purchase commitments from the Company. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;i&gt;Series B Preferred Stock &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   In March 1999, the Company issued 3,327 shares of the Company&amp;#8217;s Series B preferred stock to Fenwal, Inc. (&amp;#8220;Fenwal&amp;#8221;) (formerly, Baxter International Inc.). The Series B preferred stock had
   no voting rights, except with respect to the authorization of any class or series of stock having preference or priority over the Series B preferred stock as to voting, liquidation or conversion or with respect to the determination of fair value of
   non-publicly traded shares received by the holder of Series B preferred stock in the event of a liquidation, or except as required by Delaware law. At any time, the holder had the ability to convert each share of Series B preferred stock into 100
   shares of the Company&amp;#8217;s common stock. The Company had the right to redeem the Series B preferred stock prior to conversion for a payment of $9.5 million. In June 2012, Fenwal exercised its right to convert all 3,327 shares of the Company&amp;#8217;s
   Series B preferred stock. As a result, the Company issued 332,700 shares of its common stock to Fenwal and retired the outstanding Series B preferred stock. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:18px;margin-bottom:0px; margin-left:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   &lt;i&gt;Common Stock and Associated Warrant Liability &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In August 2009, the Company
   issued warrants to purchase 2.4&amp;#160;million shares of common stock, exercisable at an exercise price of $2.90 per share (&amp;#8220;2009 Warrants&amp;#8221;). The 2009 Warrants are exercisable for a period of five years from the issue date. The fair value on
   the date of issuance of the 2009 Warrants was determined to be $2.8 million using the binomial-lattice option valuation model and applying the following assumptions: (i)&amp;#160;a risk-free rate of 2.48%, (ii)&amp;#160;an expected term of 5.0 years,
   (iii)&amp;#160;no dividend yield and (iv)&amp;#160;a volatility of 77%. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In November 2010, the Company issued warrants to purchase
   3.7&amp;#160;million shares of common stock, exercisable at an exercise price of $3.20 per share (&amp;#8220;2010 Warrants&amp;#8221;). The 2010 Warrants became exercisable on May&amp;#160;15, 2011 and are exercisable for a period of five years from the issue date.
   The fair value on the date of issuance of the 2010 Warrants was determined to be $5.8 million using the binomial-lattice option valuation model and applying the following assumptions: (i)&amp;#160;a risk-free rate of 1.23%, (ii)&amp;#160;an expected term of
   5.0 years, (iii)&amp;#160;no dividend yield and (iv)&amp;#160;a volatility of 85%. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The fair value of the 2009 Warrants and 2010
   Warrants was recorded on the condensed consolidated balance sheets as a liability pursuant to &lt;i&gt;&amp;#8220;Accounting for Derivative Instruments and Hedging Activities&amp;#8221;&lt;/i&gt; and &lt;i&gt;&amp;#8220;Accounting for Certain Financial Instruments with
   Characteristics of Both Liabilities and Equity&amp;#8221;&lt;/i&gt; Topics of ASC and will be adjusted to fair value at each financial reporting date thereafter until the earlier of exercise or modification to remove the provisions which require the warrants
   to be treated as a liability, at which time, these warrants would be reclassified into stockholders&amp;#8217; equity. The Company classified the 2009 Warrants and 2010 Warrants as a liability as these warrants contain certain provisions that, under
   certain circumstances, which may be out of the Company&amp;#8217;s control, could require the Company to pay cash to settle the exercise of the warrants or may require the Company to redeem the warrants. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The fair value of the warrants at September&amp;#160;30, 2012, and December&amp;#160;31, 2011,
   consisted of the following (in thousands): &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company recorded non-cash gains of $0.9 million and $5.4 million during the three months ended September&amp;#160;30,
   2012, and 2011, respectively, and minimal amounts and $3.8 million during the nine months ended September&amp;#160;30, 2012, and 2011, respectively, in &amp;#8220;Revaluation of warrant liability&amp;#8221; on the condensed consolidated statements of operations
   due to the changes in fair value of the warrants. Significant changes to the Company&amp;#8217;s market price for its common stock will impact the implied and/or historical volatility used to fair value the warrants. As a result, any significant increases in the Company&amp;#8217;s stock price will likely create an increase to the fair value of warrant liability. Similarly, any significant
   decreases in the Company&amp;#8217;s stock price will likely create a decrease to the fair value of warrant liability. In June 2012, the 2010 Warrants to purchase 5,084 shares of common stock were exercised. At December&amp;#160;31, 2011, no warrants had
   been exercised. &lt;/font&gt;&lt;/p&gt;

   The Company entered into an At-The-Market Issuance Sales Agreement in June 2011, as amended in January 2012 and August 2012 (collectively, the &amp;#8220;MLV Agreement&amp;#8221;), with MLV&amp;#160;&amp;#038; Co. LLC,
   formerly McNicoll, Lewis&amp;#160;&amp;#038; Vlak LLC (&amp;#8220;MLV&amp;#8221;) that provides for the issuance and sale of shares of the Company&amp;#8217;s common stock over the term of the MLV Agreement having an aggregate offering price of up to $20.0 million through
   MLV. Under the MLV Agreement, MLV acts as the Company&amp;#8217;s sales agent and receives compensation based on an aggregate of 3% of the gross proceeds on the sale price per share of its common stock. The issuance and sale of these shares by the
   Company pursuant to the MLV Agreement are deemed an &amp;#8220;at-the-market&amp;#8221; offering and are registered under the Securities Act. During the year ended December&amp;#160;31, 2011, approximately 3.5&amp;#160;million shares of the Company&amp;#8217;s common

   for aggregate net proceeds of $9.5 million. The Company did not sell any shares of its common stock under the MLV Agreement during the three months ended September&amp;#160;30, 2012. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%;padding-bottom:0px;"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company also entered into a Controlled Equity Offering&lt;/font&gt;&lt;font style="font-family:times new roman" size="1"&gt;&lt;sup&gt;

   (&amp;#8220;Cantor&amp;#8221;) that provides for the issuance and sale of shares of its common stock over the term of the Cantor Agreement having an aggregate offering price of up to $30.0 million through Cantor. Under the Cantor Agreement, Cantor also acts
   as the Company&amp;#8217;s sales agent and receives compensation based on an aggregate of 2% of the gross proceeds on the sale price per share of its common stock. The issuance and sale of these shares by the Company pursuant to the Cantor Agreement are
   deemed an &amp;#8220;at-the-market&amp;#8221; offering and are registered under the Securities Act. During the three and nine months ended September&amp;#160;30, 2012, approximately 0.4&amp;#160;million shares of the Company&amp;#8217;s common stock were sold under the
   Cantor Agreement for aggregate net proceeds of $1.1 million. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In October 2009, the Company&amp;#8217;s Board of Directors adopted an amendment to its 1999 stockholder rights plan, commonly referred to as a
   &amp;#8220;poison pill,&amp;#8221; to reduce the exercise price, extend the expiration date and revise certain definitions under the plan. The stockholder rights plan is intended to deter hostile or coercive attempts to acquire the Company. The stockholder
   rights plan enables stockholders to acquire shares of the Company&amp;#8217;s common stock, or the common stock of an acquirer, at a substantial discount to the public market price should any person or group acquire more than 15% of the Company&amp;#8217;s
   common stock without the approval of the Board of Directors under certain circumstances. The Company has designated 250,000 shares of Series C Junior Participating preferred stock for issuance in connection with the stockholder rights plan.

   &lt;p style="margin-top:18px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Note 11. Stock-Based Compensation &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company maintains an equity compensation plan to provide long-term incentives for employees, contractors, and
   members of its Board of Directors. The Company currently grants equity awards from one plan, the 2008 Equity Incentive Plan (the &amp;#8220;2008 Plan&amp;#8221;). The 2008 Plan allows for the issuance of non-statutory and incentive stock options, restricted
   stock, restricted stock units, stock appreciation rights, other stock-related awards, and performance awards which may be settled in cash, stock, or other property. The Company continues to have equity awards outstanding under its previous stock
   plans: 1998 Non-Officer Stock Option Plan and 1999 Equity Incentive Plan (collectively, the &amp;#8220;Prior Plans&amp;#8221;) and 1996 Equity Incentive Plan (the &amp;#8220;1996 Plan&amp;#8221;). Equity awards issued under the Prior Plans and the 1996 Plan continue to
   adhere to the terms of those respective stock plans and no further options may be granted under those previous plans. However, at June&amp;#160;2, 2008, any shares that remained available for future grants under the Prior Plans became available for
   issuance under the 2008 Plan. On June&amp;#160;6, 2012, the stockholders approved an amendment to the 2008 Plan (&amp;#8220;Amended 2008 Plan&amp;#8221;) which increased the aggregate number of shares of common stock authorized for issuance by 3,000,000 shares,
   such that the Amended 2008 Plan has reserved for issuance an amount not to exceed 13,540,940 shares. At September&amp;#160;30, 2012, the Company had an aggregate of approximately 13.0&amp;#160;million shares of its common stock reserved for issuance under
   the Amended 2008 Plan, the Prior Plans and the 1996 Plan, of which approximately 8.8&amp;#160;million shares were subject to outstanding options and other stock-based awards, and approximately 4.2&amp;#160;million shares were available for future issuance
   under the Amended 2008 Plan. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company also maintains an Employee Stock Purchase Plan (the &amp;#8220;Purchase Plan&amp;#8221;) which
   is intended to qualify as an employee stock purchase plan within the meaning of Section&amp;#160;423(b) of the Internal Revenue Code. Under the Purchase Plan, the Company&amp;#8217;s Board of Directors may authorize participation by eligible employees,
   including officers, in periodic offerings. On June&amp;#160;6, 2012, the stockholders approved an amendment to the Purchase Plan to increase the aggregate number of shares of common stock authorized for issuance by 500,000 shares, such that the Purchase
   Plan has reserved for issuance an amount not to exceed 1,320,500 shares. At September&amp;#160;30, 2012, the Company had approximately 0.6&amp;#160;million shares available for future issuance under the Purchase Plan. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;&amp;#160;&lt;/p&gt;
   &lt;p style="margin-top:0px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company has
   granted restricted stock units primarily to its senior management in accordance with the Amended 2008 Plan. Subject to each grantee&amp;#8217;s continued employment, the restricted stock units generally vest in three annual installments from the date of
   grant and are generally issuable at the end of the three-year vesting term. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company currently uses the Black-Scholes option pricing model to determine the grant-date fair value of stock
   options and employee stock purchase plan shares. The Black-Scholes option pricing model is affected by the Company&amp;#8217;s stock price, as well as assumptions regarding a number of complex and subjective variables, which include the expected term of
   the grants, actual and projected employee stock option exercise behaviors, including forfeitures, the Company&amp;#8217;s expected stock price volatility, the risk-free interest rate and expected dividends. The Company recognizes the grant-date fair
   value of the stock award as stock-based compensation expense on a straight-line basis over the requisite service period, which is the vesting period, and is adjusted for estimated forfeitures. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;As a result of Baxter International Inc.&amp;#8217;s sale of its transfusion therapies division in 2007 to Fenwal, the
   Company has certain agreements with Fenwal which require the Company to pay royalties on future INTERCEPT Blood System product sales at royalty rates that vary by product: 10% of product sales for the platelet system, 3% of product sales for the
   plasma system, 5% of product sales for the red blood cell system, and 6.5% on sales of illuminators. During the three months ended September&amp;#160;30, 2012, and 2011, the Company made royalty payments to Fenwal of $0.7 million and $0.6 million,
   respectively, and $2.1 million and $1.6 million, during the nine months ended September&amp;#160;30, 2012, and 2011, respectively. At both September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the Company owed Fenwal $0.7 million for royalties.
   &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;In December 2008, the Company extended its agreement with Fenwal to manufacture finished INTERCEPT disposable kits for the
   platelet and plasma systems through December&amp;#160;31, 2013. Under the amended manufacturing and supply agreement, the Company pays Fenwal a set price per kit, which is established annually, plus a fixed surcharge per kit. In addition, volume driven
   manufacturing overhead is to be paid or refunded if actual manufacturing volumes are lower or higher than the estimated production volumes. The Company made payments to Fenwal of $1.4 million and $2.1 million relating to the manufacturing of the
   Company products during the three months ended September&amp;#160;30, 2012, and 2011, respectively, and $8.9 million and $8.5 million, during the nine months ended September&amp;#160;30, 2012, and 2011, respectively. At September&amp;#160;30, 2012, and
   December&amp;#160;31, 2011, the Company owed Fenwal $5.1 million and $3.4 million, respectively, for INTERCEPT disposable kits manufactured. In connection with the warranty claims incurred by the Company and remediation of those claims during the three
   months ended September&amp;#160;30, 2012 (see Note 1 in the Notes to Condensed Consolidated Financial Statements under &amp;#8220;Guarantee and Indemnification Arrangements&amp;#8221; for more detail), the Company filed a warranty claim against Fenwal. Fenwal has
   accepted the warranty claim and will supply the Company with replacement product or credit notes. As a result, the Company recorded a current asset of $1.7 million on its condensed consolidated balance sheets as of September&amp;#160;30, 2012
   representing the full amount of the warranty claim against Fenwal. &lt;/font&gt;&lt;/p&gt;

   responsible for the commercialization efforts of the platelet and plasma systems in Europe, The Commonwealth of Independent States and the Middle East. Product revenues are attributed to each region based on the location of the customer, and in the
   case of non-product revenues, on the location of the collaboration partner. &lt;/font&gt;&lt;/p&gt;

   during the three months ended September&amp;#160;30, 2011. The Company did not recognize any revenue from government grants and cooperative agreements during the three months ended September&amp;#160;30, 2012. The Company has historically received awards
   under cooperative agreements with the Army Medical Research Acquisition Activity division of the Department of Defense since February 2001. The Company received these awards in order to develop its pathogen inactivation technologies for the improved
   safety and availability of blood that may be used by the United States Armed Forces for medical transfusions. Under the terms of the cooperative agreements, the Company conducted research on the inactivation of infectious pathogens in blood,
   including unusual viruses, bacteria and parasites that were of concern to the United States Armed Forces. This funding supported the development of the Company&amp;#8217;s red blood cell system. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px"&gt;&lt;font style="font-family:times new roman" size="2"&gt;&lt;b&gt;Principles of Consolidation and Basis of Presentation &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The accompanying unaudited condensed consolidated financial statements include those of Cerus Corporation and its subsidiary, Cerus Europe
   B.V. (collectively referred to hereinafter as &amp;#8220;Cerus&amp;#8221; or the &amp;#8220;Company&amp;#8221;) after elimination of all intercompany accounts and transactions. These condensed consolidated financial statements have been prepared in accordance with
   accounting principles generally accepted in the United States of America (&amp;#8220;GAAP&amp;#8221;) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (&amp;#8220;SEC&amp;#8221;). Accordingly, they do
   not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring entries, considered necessary for a fair presentation have been made.
   Operating results for the three and nine months ended September&amp;#160;30, 2012, are not necessarily indicative of the results that may be expected for the year ending December&amp;#160;31, 2012, or for any future periods. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;As previously reported in Note 20, Quarterly Financial Information, in the Notes to Consolidated Financial Statements included in the
   Company&amp;#8217;s 2011 Annual Report on Form 10-K for the year ended December&amp;#160;31, 2011, filed with the SEC on March&amp;#160;5, 2012, the Company restated previously reported financial statements for the three and nine months ended September&amp;#160;30,
   2011. The adjustments related to previously capitalized inventory costs, which should have been charged to cost of product revenue as products were sold. Although the correction was immaterial to the three and nine months ended September&amp;#160;30,
   2011, the Company decided to restate the amounts previously reported to better reflect the actual operating trends of the Company&amp;#8217;s business for 2011. The adjustments primarily increased cost of product revenue by $0.1 million and $0.3 million
   for the three and nine months ended September&amp;#160;30, 2011, respectively. The offsetting adjustment entry was a reduction to the carrying value of inventory. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   These condensed consolidated financial statements and notes thereto should be read in conjunction with the Company&amp;#8217;s audited financial statements and notes thereto for the year ended
   December&amp;#160;31, 2011, which were included in the Company&amp;#8217;s 2011 Annual Report on Form 10-K, filed with the SEC on March&amp;#160;5, 2012. The accompanying balance sheet as of December&amp;#160;31, 2011, has been derived from the Company&amp;#8217;s
   audited financial statements as of that date. &lt;/font&gt;&lt;/p&gt;

   The preparation of financial statements requires management to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related
   disclosures of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates, which are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual
   results may differ from those estimates under different assumptions or conditions. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company recognizes revenue in accordance with ASC Topic 605-25, &lt;i&gt;&amp;#8220;Revenue Recognition &amp;#8211; Arrangements with Multiple
   Deliverables,&amp;#8221;&lt;/i&gt; as applicable. Revenue is recognized when (i)&amp;#160;persuasive evidence of an agreement with the funding party exists; (ii)&amp;#160;services have been rendered or product has been delivered; (iii)&amp;#160;pricing is fixed or
   determinable; and (iv)&amp;#160;collection is reasonably assured. The Company&amp;#8217;s main sources of revenues for the three and nine months ended September&amp;#160;30, 2012, and 2011, were product revenue from sales of the INTERCEPT Blood System for
   platelets and plasma (&amp;#8220;platelet and plasma systems&amp;#8221;) and United States government grants and awards. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Revenue
   related to product sales is generally recognized when the Company fulfills its obligations for each element of an agreement. For all sales of the Company&amp;#8217;s INTERCEPT Blood System products, the Company uses a binding purchase order and signed
   sales contract as evidence of a written agreement. The Company sells its platelet and plasma systems directly to blood banks, hospitals, universities, government agencies, as well as to distributors in certain regions. Generally, the Company&amp;#8217;s
   contracts with its customers do not provide for open return rights, except within a reasonable time after receipt of goods in the case of defective or non-conforming product. Deliverables and the units of accounting vary according to the provisions
   of each purchase order or sales contract. For revenue arrangements with multiple elements, the Company determines whether the delivered elements meet the criteria as separate units of accounting. Such criteria require that the deliverable have
   stand-alone value to the customer and that if a general right of return exists relative to the delivered item, delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. Once the
   Company determines if the deliverable meets the criteria for a separate unit of accounting, the Company must determine how the consideration should be allocated between the deliverables and how the separate units of accounting should be recognized
   as revenue. Consideration received is allocated to elements that are identified as discrete units of accounting based on the best estimated selling price. The Company has determined that vendor specific objective evidence is not discernible due to the Company&amp;#8217;s limited history of selling its products and variability in
   its pricing across the regions into which it sells its products. Since the Company&amp;#8217;s products are novel and unique and are not sold by others, third-party evidence of selling price is unavailable. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Investments with original maturities of greater than three months but less than one year from the date of purchase as well as
   available-for-sale investments with original maturities of greater than one year from the date of purchase, which included United States government agency securities, are classified as short-term investments. In accordance with ASC Topic 320,
   &lt;i&gt;&amp;#8220;Accounting for Certain Investments in Debt and Equity Securities,&amp;#8221;&lt;/i&gt; the Company has classified all debt securities as available-for-sale at the time of purchase and reevaluates such designation as of each balance sheet date.
   Available-for-sale securities are carried at estimated fair value. Unrealized gains and losses derived by changes in the estimated fair value of available-for-sale securities are recorded in &amp;#8220;Accumulated other comprehensive income&amp;#8221; on the
   Company&amp;#8217;s condensed consolidated balance sheets and/or in &amp;#8220;Net unrealized losses on available-for-sale securities, net of taxes&amp;#8221; on the Company&amp;#8217;s condensed consolidated statements of comprehensive income (loss). Realized gains

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents,
   short-term investments and accounts receivable. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Pursuant to the Company&amp;#8217;s investment policy, substantially all of the
   Company&amp;#8217;s cash, cash equivalents and short-term investments are maintained at a major financial institution of high credit standing. The Company monitors the financial credit worthiness of the issuers of its investments and limits the
   concentration in individual securities and types of investments that exist within its investment portfolio. Generally, all of the Company&amp;#8217;s investments carry high credit quality ratings, which is in accordance with its investment policy. At
   September&amp;#160;30, 2012, the Company does not believe there is significant financial risk from non-performance by the issuers of the Company&amp;#8217;s cash equivalents. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   Concentrations of credit risk with respect to trade receivables exist. However, in connection with the Company&amp;#8217;s revolving line of credit, as discussed in Note 8 in the Notes to Condensed
   Consolidated Financial Statements, the Company purchased a credit insurance policy that mitigates some of its credit risk, as the policy will pay either the Company or its lender on eligible claims filed on its outstanding receivables. On a regular
   basis, including at the time of sale, the Company performs credit evaluations of its customers. Generally, the Company does not require collateral from its customers to secure accounts receivable. To the extent that the Company determines specific
   invoices or customer accounts may be uncollectible, the Company reserves against the accounts receivable on its condensed consolidated balance sheets and records a charge on its condensed consolidated statements of operations. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company had three customers and two customers that accounted for more than 10% of the Company&amp;#8217;s outstanding trade receivables at
   September&amp;#160;30, 2012, and December&amp;#160;31, 2011, respectively. These customers cumulatively represented approximately 69% and 58% of the Company&amp;#8217;s outstanding trade receivables at September&amp;#160;30, 2012, and December&amp;#160;31, 2011,
   respectively. To date, the Company has not experienced collection difficulties from these customers. &lt;/font&gt;&lt;/p&gt;

   At September&amp;#160;30, 2012, and December&amp;#160;31, 2011, inventory consisted of work-in-process and finished goods only. Finished goods include INTERCEPT disposable kits, UVA illumination devices
   (&amp;#8220;illuminators&amp;#8221;), and certain replacement parts for the illuminators. Platelet and plasma systems&amp;#8217; disposable kits generally have a two-year life from the date of manufacture. Illuminators and replacement parts do not have regulated
   expiration dates. Work-in-process includes certain components that are manufactured over a protracted length of time, which can exceed one year, before being incorporated and assembled by Fenwal, Inc. (&amp;#8220;Fenwal&amp;#8221;) into the finished INTERCEPT
   disposable kits. The Company maintains an inventory balance based on its current sales projections, and at each reporting period, the Company evaluates whether its work-in-process inventory would be consumed for production of finished units in order
   to sell to existing and prospective customers within the next twelve-month period. It is not customary for the Company&amp;#8217;s production cycle for inventory to exceed twelve months. Instead, the Company uses its best judgment to factor in lead times
   for the production of its finished units to meet the Company&amp;#8217;s current demands. If actual results differ from those estimates, work-in-process inventory could potentially accumulate for periods exceeding one year. At September&amp;#160;30, 2012,
   and December&amp;#160;31, 2011, the Company classified its work-in-process inventory as a current asset on its condensed consolidated balance sheets based on its evaluation that the work-in-process inventory would be consumed for production and
   subsequently sold within each respective subsequent twelve-month period. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Inventory is recorded at the lower of cost,
   determined on a first-in, first-out basis, or market value. The Company uses significant judgment to analyze and determine if the composition of its inventory is obsolete, slow-moving or unsalable and frequently reviews such determinations. The
   Company&amp;#8217;s limited history selling the INTERCEPT Blood System limits the amount of historical data the Company has to perform this analysis. Generally, the Company writes-down specifically identified unusable, obsolete, slow-moving, or known
   unsalable inventory that has no alternative use in the period that it is first recognized by using a number of factors including product expiration dates, open and unfulfilled orders, and sales forecasts. Any write-down of its inventory to net
   realizable value establishes a new cost basis and will be maintained even if certain circumstances suggest that the inventory is recoverable in subsequent periods. Costs associated with the write-down of inventory are recorded in &amp;#8220;Cost of
   product revenue&amp;#8221; on the Company&amp;#8217;s condensed consolidated statements of operations. At September&amp;#160;30, 2012, and December&amp;#160;31, 2011, the Company had $0.3 million and $0.6 million, respectively, reserved for potential obsolete,
   expiring or unsalable product. At September&amp;#160;30, 2012, the Company also wrote-down the value of certain unsaleable inventory of $1.1 million for which the Company has an offsetting warranty claim against Fenwal. See below in Note 1 in the Notes
   to Condensed Consolidated Financial Statements under &amp;#8220;Guarantee and Indemnification Arrangements&amp;#8221; and Note 12 in the Notes to Condensed Consolidated Financial Statements for further information regarding the Company&amp;#8217;s warranty claim
   with Fenwal. &lt;/font&gt;&lt;/p&gt;

   impairment test performed on an annual basis, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Such impairment analysis is performed on August&amp;#160;31 of each fiscal year, or more frequently if
   indicators of impairment exist. Effective January&amp;#160;1, 2012, the test for goodwill impairment may be assessed using qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the
   carrying amount. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than the carrying amount, the Company must then proceed with performing the quantitative two-step process to test goodwill for
   impairment; otherwise, goodwill is not considered impaired and no further testing is warranted. The Company may choose not to perform the qualitative assessment to test goodwill for impairment and proceed directly to the quantitative two-step
   process; however, the Company may revert to the qualitative assessment to test goodwill for impairment in any subsequent period. The first step of the two-step process compares the fair value of each reporting unit with its respective carrying
   amount, including goodwill. The Company has determined that it operates in one reporting unit and estimates the fair value of its one reporting unit using the enterprise approach under which it considers the quoted market capitalization of the
   Company as reported on the Nasdaq Global Market. The Company considers quoted market prices that are available in active markets to be the best evidence of fair value. The Company also considers other factors, which include future forecasted
   results, the economic environment and overall market conditions. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired and, therefore, the second step of the impairment test is
   unnecessary. The second step of the two-step process, which is used to measure the amount of impairment loss, compares the implied fair value of each reporting unit&amp;#8217;s goodwill with the respective carrying amount of that goodwill. If the
   carrying amount of the reporting unit&amp;#8217;s goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   The Company performs an impairment test on its intangible assets, in accordance ASC Topic 360-10, &lt;i&gt;&amp;#8220;Property, Plant and Equipment,&amp;#8221;&lt;/i&gt; if certain events or changes in circumstances occur
   which indicate that the carrying amounts of its intangible assets may not be recoverable. If the intangible assets are not recoverable, an impairment loss would be recognized by the Company based on the excess amount of the carrying value of the
   intangible assets over its fair value. For further details regarding the impairment analysis, reference is made to the section below under &amp;#8220;Long-lived Assets.&amp;#8221; Also, see Note 5 in the Notes to Condensed Consolidated Financial Statements

   undiscounted expected future cash flows. If the expected undiscounted future cash flows are less than the carrying amount of these assets, the Company then measures the amount of the impairment loss based on the excess of the carrying amount over

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;
   In August 2009, and November 2010, the Company issued warrants to purchase an aggregate of 2.4&amp;#160;million and 3.7&amp;#160;million shares of common stock, respectively. The material terms of the warrants
   were identical under each issuance except for the exercise price, date issued and expiration date. The Company classifies the warrants as a liability on its condensed consolidated balance sheets as the warrants contain certain material terms which
   require the Company (or its successor) to purchase the warrants for cash in an amount equal to the value of the unexercised portion of the warrants (as determined in accordance with the Black-Scholes option pricing model) in connection with certain
   change of control transactions. In addition, the Company may also be required to pay cash to a warrant holder under certain circumstances if the Company is unable to timely deliver the shares acquired upon warrant exercise to such holder.
   &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The fair value of these outstanding warrants is calculated using the binomial-lattice option-pricing model and is adjusted
   accordingly at each reporting period. The binomial-lattice option-pricing model requires that the Company uses significant assumptions and judgment to determine appropriate inputs to the model. Some of the assumptions that the Company relies on
   include the probability of a change of control occurring, the volatility of the Company&amp;#8217;s stock over the life of the warrant and assumptions and inputs used to value the warrants under the Black-Scholes model should a change of control occur.
   &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Changes resulting from the revaluation of warrants to fair value are recorded in &amp;#8220;Revaluation of warrant liability&amp;#8221;
   on the condensed consolidated statements of operations. Upon the exercise or modification to remove the provisions which require the warrants to be treated as a liability, the fair value of the warrants will be reclassified from a liability to
   stockholders&amp;#8217; equity on the Company&amp;#8217;s condensed consolidated balance sheets and no further adjustment to the fair value would be made in subsequent periods. &lt;/font&gt;&lt;/p&gt;

   The Company accounts for income taxes using an asset and liability approach in accordance with ASC Topic 740 &lt;i&gt;&amp;#8220;Accounting for Income Taxes.&amp;#8221;&lt;/i&gt; Under this method, deferred tax assets and
   liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. ASC
   Topic 740 requires derecognition of tax positions that do not have a greater than 50% likelihood of being recognized upon review by a taxing authority having full knowledge of all relevant information. Use of a valuation allowance as described in
   ASC Topic 740 is not an appropriate substitute for the derecognition of a tax position. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in its income tax expense. To date, the Company has not recognized any
   interest and penalties in its condensed consolidated statements of operations, nor has its accrued for or made payments for interest and penalties. The Company continues to carry a full valuation allowance on all of its deferred tax assets. Although
   the Company believes it more likely than not that a taxing authority would agree with its current tax positions, there can be no assurance that the tax positions the Company has taken will be substantiated by a taxing authority if reviewed. The
   Company&amp;#8217;s tax years 2007 through 2011 remain subject to examination by the taxing jurisdictions. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares
   outstanding for the period. Diluted net income (loss) per common share gives effect to all potentially dilutive common shares outstanding for the period. The potentially dilutive securities include stock options, employee stock purchase plan rights,
   warrants and restricted stock units, which are calculated using the treasury stock method, and convertible preferred stock, which is calculated using the if-converted method. Diluted net income (loss) per common share also gives effect to potential
   adjustments to the numerator for changes resulting from the revaluation of warrants to fair value for the period, even if the Company is in a net loss position if the effect would result in more dilution. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;Diluted net loss per common share used the same weighted average number of common shares outstanding for the nine months ended
   September&amp;#160;30, 2012, and 2011, as calculated for the basic net loss per common share as the inclusion of any potential dilutive securities would be anti-dilutive. In addition, certain potential dilutive securities were excluded from the dilution
   calculation for the three months ended September&amp;#160;30, 2012, and 2011, as their inclusion would have been anti-dilutive. &lt;/font&gt;&lt;/p&gt;

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company recognizes the fair value for guarantee and indemnification arrangements issued or modified by the Company after
   December&amp;#160;31, 2002. In addition, the Company monitors the conditions that are subject to the guarantees and indemnifications in order to identify if a loss has occurred. If the Company determines it is probable that a loss has occurred, then any
   such estimable loss would be recognized under those guarantees and indemnifications. Some of the agreements that the Company is a party to contain provisions that indemnify the counter party from damages and costs resulting from claims that the
   Company&amp;#8217;s technology infringes the intellectual property rights of a third party or claims that the sale or use of the Company&amp;#8217;s products have caused personal injury or other damage or loss. The Company has not received any such requests
   for indemnification under these provisions and has not been required to make material payments pursuant to these provisions. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company generally provides for a one-year warranty on certain of its INTERCEPT blood-safety products covering defects in materials
   and workmanship. The Company accrues costs associated with warranty obligations when claims become known and are estimable. During the three months ended September&amp;#160;30, 2012, the Company provided for warranty obligations related to replacement
   costs for certain of its products that the Company identified were defective or had the potential of being defective. Prior to this incident, there have been very few warranty costs incurred. As a result, the Company had not accrued for any
   potential future warranty costs at December&amp;#160;31, 2011. In addition, the Company believes that the defective products and those that had the potential of being defective identified during the three months ended September&amp;#160;30, 2012 are
   isolated. Accordingly, the Company has not accrued for any other incremental potential future warranty costs for its products at September&amp;#160;30, 2012. The product warrant liability is recorded in &amp;#8220;Accrued liabilities&amp;#8221; on the
   Company&amp;#8217;s condensed consolidated balance sheets.
   A reconciliation of changes to the beginning and ending balances of the Company&amp;#8217;s product warranty liability, from December&amp;#160;31, 2011, to September&amp;#160;30, 2012, was as follows

   &lt;p style="margin-top:6px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;The Company applies the provisions of fair value relating to its financial assets and liabilities. The carrying amounts of accounts
   receivables, accounts payable, and other accrued liabilities approximate their fair value due to the relative short-term maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes
   the fair value of its debt approximates their carrying amounts. The Company measures and records certain financial assets and liabilities at fair value on a recurring basis, including its available-for-sale securities and warrant liability. The
   Company classifies instruments within Level 1 if quote prices are available in active markets, which include its money market funds as the maturity of money market funds are relatively short and the carrying amount is a reasonable estimate of fair
   value. The Company classifies instruments in Level 2 if the instruments are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of
   price transparency. These instruments include the Company&amp;#8217;s available-for-sale securities related to United States government agencies. The available-for-sale securities are held by a custodian who obtains investment prices from a third party
   pricing provider that uses standard inputs to models which vary by asset class. The Company classifies instruments in Level 3 if one or more significant inputs or significant value drivers are unobservable, which include its warrant liability. The
   Company assesses any transfers among fair value measurement levels at the end of each reporting period. &lt;/font&gt;&lt;/p&gt;
   &lt;p style="margin-top:12px;margin-bottom:0px; text-indent:8%"&gt;&lt;font style="font-family:times new roman" size="2"&gt;See Note 2 and 10 in
