Purified from fresh frozen human plasma. Human Prekallikrein is a single chain gamma globulin glycoprotein that participates in the early phase of contact activation, kinin formation and fibrinolysis. Purified Prekallikrein has a specific clotting activity of approximately 25 u/mg. Prekallikrein is homogeneous as judged by 10% SDS-PAGE gels and shows no reduction upon incubation with 2-mercaptoethanol.
