Plasmin Antiactivator; alpha(2)-Plasmin Inhibitor; alpha-2 Antiplasmin; alpha-2-Antiplasmin; Antiactivator, Plasmin; Antiplasmin, alpha-2; Inhibitor, alpha 2-Plasmin; alpha 2 Antiplasmin; alpha 2 Plasmin Inhibitor
A member of the serpin superfamily found in human plasma that inhibits the lysis of fibrin clots which are induced by plasminogen activator. It is a glycoprotein, molecular weight approximately 70,000 that migrates in the alpha 2 region in immunoelectrophoresis. It is the principal plasmin inactivator in blood, rapidly forming a very stable complex with plasmin.
