Human Prothrombin (Factor II)

Catalogue Number: HP 1002
Size: 9.0 mg

Prepared from fresh frozen human plasma. Human Prothrombin is a glycoprotein of molecular weight 72,000 and consists of a single polypeptide chain. Activation of Human Prothrombin by Human Factor Va, Human Factor Xa and phospholipids yields the serine protease Human Alpha Thrombin. Human Prothrombin purity is determined by SDS-PAGE and shows no reduction upon incubation with 2-mercaptoethanol.
