Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes As of December 31, 2013, the Company had approximately $110.6 million of Federal NOLs available to offset future taxable income expiring from 2025 through 2033. In accordance with Section 382 of the Internal Revenue code, the usage of the Company’s NOLs could be limited in the event of a change in ownership. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period when those temporary differences become deductible. If a change of ownership did occur there would be an annual limitation on the usage of the Company’s losses which are available through 2033. In assessing the realizability of deferred tax assets, including the net operating loss carryforwards ("NOLs"), the Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize its existing deferred tax assets. Based on its assessment, the Company has provided a full valuation allowance against its net deferred tax assets as their future utilization remains uncertain at this time. Deferred tax liabilities were $19.0 million and $4.4 million as of June 30, 2014 and December 31, 2013, and relate to the taxable temporary differences on (i) the goodwill recognized in the PCT acquisition in 2011, (ii) the in-process R&D intangible asset recognized in the Amorcyte acquisition in 2011, and (iii) the in-process R&D intangible asset recognized in the CSC acquisition in 2014. The taxable temporary difference associated with the goodwill, which is tax deductible and will be amortized over 15 years, will continue to increase the deferred tax liability balance over the amortization period, with an associated charge to the tax provision in each period. The deferred tax liabilities will only reverse when these indefinite-lived assets are sold, impaired, or reclassified from an indefinite-lived asset to a finite-lived asset. As of June 30, 2014, management does not believe the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary. The Company does not believe there will be any material changes in its unrecognized tax positions over the next year.

As of December 31, 2013, the Company had approximately $110.6 million of Federal NOLs available to offset future taxable income expiring from 2025 through 2033. In accordance with Section 382 of the Internal Revenue code, the usage of the Company’s NOLs could be limited in the event of a change in ownership. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period when those temporary differences become deductible. If a change of ownership did occur there would be an annual limitation on the usage of the Company’s losses which are available through 2033.

In assessing the realizability of deferred tax assets, including the net operating loss carryforwards ("NOLs"), the Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize its existing deferred tax assets. Based on its assessment, the Company has provided a full valuation allowance against its net deferred tax assets as their future utilization remains uncertain at this time.

Deferred tax liabilities were $19.0 million and $4.4 million as of June 30, 2014 and December 31, 2013, and relate to the taxable temporary differences on (i) the goodwill recognized in the PCT acquisition in 2011, (ii) the in-process R&D intangible asset recognized in the Amorcyte acquisition in 2011, and (iii) the in-process R&D intangible asset recognized in the CSC acquisition in 2014.

The deferred tax liabilities will only reverse when these indefinite-lived assets are sold, impaired, or reclassified from an indefinite-lived asset to a finite-lived asset.

As of June 30, 2014, management does not believe the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary.
