Complete kit for anti-IIa potency testing of Unfractionated Heparin (UFH) per both the USP (Chapter <208>) and European Pharmacopoeia (Chapter 2.7.12) methodologies. Chromogenic endpoint or kinetic assay measuring heparin anti-FIIa (anti-thrombin) activity in the range 0.005–0.030 USP Heparin Units/mL (IU/mL).

The anti-IIa method uses a constant amount of antithrombin (AT) incubated with sample heparin. Excess thrombin (Factor IIa) is added; residual thrombin cleaves a chromogenic thrombin substrate — colour intensity inversely proportional to heparin concentration, measured at 405 nm.

• Dual pharmacopoeial compliance: USP Chapter <208> and Ph. Eur. Chapter 2.7.12
• Range: 0.005–0.030 IU/mL anti-IIa
• For UFH raw material and finished product potency research
