Factor V Activator (RVV-V), 1000 U, lyophilized

Specific factor V activator from Russell’s viper venom (RVV-V). RVV-V is a serine proteinase, which converts the single-chain coagulation factor V into a light chain (80 kDa) and a heavy chain (230 kDa) with higher coagulant activity (factor Va). Apart from factor V, no other protein substrate for RVV-V is known. The amino acid sequence is 68% identical to that of batroxobin and 33% to that of the ß-chain of human thrombin. The molecular weight is approximately 28 kDa.
