title: [Effect of endogenous fibrinolysis activation on human plasminogen].
abstract: Plasminogen preparation from donor blood and fibrinolytically active blood plasma from humans after sudden death were obtained using affinity chromatography on Lysin-sepharose 4B. The plasminogen preparation from donor blood was shown to be highly purified native plasminogen (Glu-plasminogen). The preparation containing activated plasminogen (Lys-plasminogen), plasmin, plasminogen activator, alpha 2-macroglobulin, alpha 1-antitrypsin, fibrin/fibrinogen was obtained from the blood plasma of humans after sudden death. The appearance of proteins lacking biological specificity to lysin-sepharose in the plasminogen preparation shows the ability of activated plasminogen and plasmin to form complexes with these proteins and demonstrates the retention of the functional activity in lysin-binding regions on their molecules. Monospecific sera to the isolated preparations were obtained, demonstrating the presence of the same immunochemical determinants in native and activated plasminogen.
