: Bovine and human blood plasma contains alpha 2-antiplasmin which possesses affinity to lysin-binding sites in plasmin and inhibits the human plasmin. Its isolation was conducted for two stages: separation of plasminogen on lysin-cellulose, fractionation by ammonium sulphate, desalination on molselector G-25, chromatography on DEAE-Sephadex A-50 and affinity chromatography on plasmin-sepharose with the blocked active site.
