The financial information filed is unaudited. The Condensed Consolidated Financial Statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for the fair statement of the results of operations for the interim periods covered and of the financial condition of the Company at the date of the interim balance sheet. The December 31, 2014 Condensed Consolidated Balance Sheet was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States of America (GAAP). The results for interim periods are not necessarily indicative of the results for the entire year or any other interim period. The Condensed Consolidated Financial Statements should be read in conjunction with the Company’s financial statements and the notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2014 filed with the Securities and Exchange Commission on March 13, 2015. |

Use of Estimates | |||||||||
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates. | |||||||||
Net Loss Per Share | |||||||||
Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. | |||||||||
Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and dilutive common stock equivalent shares outstanding for the period. The Company’s potentially dilutive common stock equivalent shares, which include incremental common shares issuable upon (i) the exercise of outstanding stock options and warrants, (ii) vesting of restricted stock units (RSUs), and (iii) the purchase from contributions to the 2012 Employee Stock Purchase Plan (the ESPP), (calculated based on the treasury stock method), are only included in the calculation of diluted net loss per share when their effect is dilutive. | |||||||||
For the three months ended March 31, 2015 and 2014, the following potentially dilutive securities were excluded from the calculation of diluted net loss per share due to their anti-dilutive effect: | |||||||||

Comprehensive Loss | |||||||||
Comprehensive loss comprises net loss and other comprehensive income. For the periods presented other comprehensive income consists of unrealized gains on the Company’s available-for-sale securities. For the three months ended March 31, 2015, amounts reclassified from accumulated other income to net income for unrealized gains (losses) on available-for-sale securities were not significant, and were recorded as part of other income (expense), net in the Condensed Consolidated Statements of Operations. For the three months ended March 31, 2014, there were no sales of investments, and therefore there were no reclassifications. |

Cash equivalents in the tables above exclude cash of $1.1 million and $0.2 million as of March 31, 2015 and December 31, 2014, respectively. All available-for-sale securities held as of March 31, 2015 had contractual maturities of less than two years. There have been no significant realized gains or losses on available-for-sale securities for the periods presented. No significant available-for-sale securities held as of March 31, 2015 have been in a continuous unrealized loss position for more than 12 months. As of March 31, 2015, unrealized losses on available-for-sale investments are not attributed to credit risk and are considered to be temporary. The Company believes that it is more-likely-than-not that investments in an unrealized loss position will be held until maturity or the recovery of the cost basis of the investment. The Company believes it has no other-than-temporary impairments on its securities because it does not intend to sell these securities and it believes it is not more likely than not that it will be required to sell these securities before the recovery of their amortized cost basis. To date, the Company has not recorded any impairment charges on marketable securities related to other-than-temporary declines in market value. |

Level 1—Inputs which include quoted prices in active markets for identical assets and liabilities. | |||||||||||||||||
Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. | |||||||||||||||||

During the three months ended March 31, 2015, there were no transfers between Level 1 and Level 2 financial assets. When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable debt instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers or brokers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data using statistical models when observable market data exists. The discounted cash flow model uses observable market inputs, such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings. |

In September 2011, the Company entered into a convertible note loan agreement with Bio-Techne Corporation, formerly Techne Corporation, (Bio-Techne), one of its principal stockholders, pursuant to which the Company issued a convertible note to Bio-Techne with a principal amount of $10.0 million and bearing interest at a rate of 5.0% per annum and a maturity date in September 2021. In February 2012, the Company completed its initial public offering (IPO), and as such, all outstanding principal and accrued and unpaid interest automatically converted into 1,021,490 shares of common stock at a conversion price equal to the IPO price of $10.00 per share.

Use of Estimates | Use of Estimates |
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates. | |
Net Loss Per Share | Net Loss Per Share |
Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. | |
Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and dilutive common stock equivalent shares outstanding for the period. The Company’s potentially dilutive common stock equivalent shares, which include incremental common shares issuable upon (i) the exercise of outstanding stock options and warrants, (ii) vesting of restricted stock units (RSUs), and (iii) the purchase from contributions to the 2012 Employee Stock Purchase Plan (the ESPP), (calculated based on the treasury stock method), are only included in the calculation of diluted net loss per share when their effect is dilutive. | |
Comprehensive Loss | Comprehensive Loss |
Comprehensive loss comprises net loss and other comprehensive income. For the periods presented other comprehensive income consists of unrealized gains on the Company’s available-for-sale securities. For the three months ended March 31, 2015, amounts reclassified from accumulated other income to net income for unrealized gains (losses) on available-for-sale securities were not significant, and were recorded as part of other income (expense), net in the Condensed Consolidated Statements of Operations. For the three months ended March 31, 2014, there were no sales of investments, and therefore there were no reclassifications. | |
Fair Value of Financial Assets and Liabilities | The Company determines the fair value of financial assets and liabilities using three levels of inputs as follows: |
Level 1—Inputs which include quoted prices in active markets for identical assets and liabilities. | |
Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. | |
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | |
Market Prices for Identical Securities | When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable debt instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data.
