Coagulation Factor V, Human Plasma

Native coagulation factor V from human plasma. Thrombin cleaves Factor V to yield activated Factor Va, which exhibits 50-fold greater activity than the precursor molecule. Factor Va, Ca²⁺, and membrane phospholipids are cofactors which form a "prothrombinase" complex with Factor Xa, enabling its proteolytic activation of prothrombin to thrombin.

Please refer to vial label for lot-specific concentration.

In 50% glycerol/H₂O (v/v).

Following initial thaw, aliquot and freeze (-20°C). Do not store below -20°C.

Prepared from plasma that has been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.

Clotting activity is determined by comparison to a standard curve produced using normal pooled human plasma
