α2-Antiplasmin (α2AP), also known as α2Plasmin Inhibitor, is a plasma glycoprotein that is a member of the SERPIN family of proteinase inhibitors.  α2AP is the primary fast-acting inhibitor of plasmin in vivo, but has also been reported to inhibit other enzymes such as trypsin, elastase, and Activated Protein C. α2AP is purified from normal human plasma using immunoaffinity and ion-exchange chromatography. Purified α2AP activity is determined by titration with purified plasmin using chromogenic substrate S-2251.
