Staphylokinase
Staphylokinase is a profibrinolytic agent that forms a 1:1 stoichiometric complex with plasminogen which, following conversion to plasmin, activates other plasminogen molecules to plasmin. The plasmin, staphylokinase complex, unlike the plasmin, streptokinase complex, is rapidly inhibited by alpha 2-antiplasmin. In a plasma milieu, staphylokinase is able to dissolve fibrin clots without associated fibrinogen degradation.
