Factor V Activating Enzyme from Russell's viper venom

lyophilized powder, 20 units/mg protein



Unit Definition

One unit will increase the Factor V activity in 0.1 mL of fresh normal human plasma by at least 2× after incubation for 3 min at 37 °C.

Physical form

Stabilized in albumin and sodium chloride.


Factor V activating enzyme from Russell’s viper venom (RVV) is a single-chain glycoprotein that is involved in the rapid clotting of blood. Factor V circulates in the blood as an inactive cofactor and must be activated by proteases such as Factor V activating enzyme from RVV . This product may be useful in studying the blood coagulation cascade as well as the inherited deficiency called parahemophilia .

Biochem/physiol Actions

Factor V activator for RVV contains fucose, mannose, galactose, glucosamine, and neuraminic acid. Factor V activating enzyme from RVV is an arginine esterase that is sensitive to diisopropyl fluorophosphate (DFP) .
