alpha 2-Plasmin inhibitor (alpha 2PI) was purified directly from human plasma by using a monoclonal antibody affinity column, which recognizes the reactive site of alpha 2PI. alpha 2PI was eluted from the column under mild conditions with 50% v/v ethyleneglycol containing 0.05% Tween 80 in phosphate-buffered saline, pH 7.4. The yield was around 50% and the specific activity of the purified protein was the same as that of the best product of preparation conventionally purified alpha 2PI.

D000979	alpha-2-Antiplasmin	A member of the serpin superfamily found in 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.	alpha 2-Plasmin Inhibitor,Serpin F2,alpha(2)-Plasmin Inhibitor,alpha-2 Antiplasmin,alpha 2 Antiplasmin,alpha 2 Plasmin Inhibitor
