RVV-Factor X

Specific factor X activator from Russell’s viper venom. RVV-X is a dimer of two peptide chains with a molecular weight of 60’000 g/mol each. Activation of factor X by RVV-X strictly depends on the presence of calcium ions. 1 unit (U) is the amount of RVV-X which generates one international unit of enzyme (factor Xa)from zymogen (factor X) [Stocker et al., 1986]. 1 vial contains 0.5 mg protein and 0.5mg stabilyzer.

RVV-X is used in diagnostic procedures to quantitatively convert the zymogen factor X into factor Xa which can be determined by means of a clotting assay or photometrically, using a synthetic
chromogenic substrate. RVV-X activator is used in testing of lupus anticoagulants.
