              Description
              OverviewA competitive and reversible inhibitor of esterases and proteases. Forms a tight complex with and blocks the active site of the enzymes. Inhibits a number of different proteases, including chymotrypsin, coagulation factors involved in the prephase of blood clotting, kallikrein (Kd = 1 x 10-7 M), plasmin (Kd = 2.3 x 10-10 M) , tissue and leukocytic proteinases, and trypsin (Kd = 5 x 10-14 M). Does not inhibit Factor Xa and thrombin. It is relatively acid- and heat-stable. Useful as a serine protease inhibitor during purification of proteins and in studies of zymogen activation systems. Reported to suppress virus HA cleavage and limit reproduction of human and avian influenza viruses with a single arginine in the HA cleavage site.
              Note: 1 KIU = 0.025 antiplasmin units (APU) = 0.0016 trypsin inhibitor units (using porcine trypsin) = 0.0009756 trypsin inhibitor units (using bovine trypsin).
              Effectively inhibits target proteases at equimolar concentration.
