Description

General description

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.

Packaging

Please refer to vial label for lot-specific concentration.

Physical form

In 50% glycerol/H₂O (v/v).

Preparation Note

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.

Analysis Note

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