A protein having human plasmin inhibiting activity, substantially equivalent reactivity with human plasmin to a human alpha 2-plasmin inhibitor derived from plasma, a binding ability to human fibrin about +E,fra 1/4+EE to about +E,fra 1/3+EE of that of the human alpha 2-plasmin inhibitor derived from plasma, and a molecular weight of about 50,000 to about 77,000. |
