Human Prekallikrein is a single chain gamma globulin glycoprotein that participates in the early phase of contract activation, kinin formation and fibrinolysis. Prekallikrein purity is determined by SDS-PAGE and shows no reduction upon incubation with 2-mercaptoethanol. Activity is determined via clotting assay.
