1-4 mg will inhibit 1.0 mg of trypsin with activity of approx. 10,000 BAEE units per mg protein. 1-6 mg will inhibit 1.0 mg of α-chymotrypsin with activity of >=40 BTEE units per mg protein.
Serine protease inhibitor; inhibits trypsin, chymotrypsin and pancreatic and granulocytic elastase, and acrosin. Effective concentration equimolar with proteinase.
Serine protease inhibitor; inhibits trypsin, chymotrypsin and pancreatic and granulocytic elastase, and acrosin. Effective concentration equimolar with proteinase.The effects of hereditary α1-antitrypsin deficiency and certain autoimmune states result from uncontrolled proteolysis in vivo. Direct α1-antitrypsin replacement therapy has shown promise in animal models of Type 1 diabetes.
Preparation Note
Chromatographically prepared and partially purified.
Disclaimer
Aqueous stock solutions containing 0.01% NaN3 are stable for several months. Solutions can be stored at −80 °C, but should not be refrozen. Unstable below pH 5.5. Inactivated by some non-serine proteinases and by oxidation of active site methionine residue.

The ability to measure protease activity in the blood is important for the development of future diagnostics and for biomedical research. Presently, protease assays require sample preparation, making them time-consuming, costly, less accurate, and unsuitable for point-of-care (POC) diagnostics. Recently

Thiourea and dimethylthiourea are powerful scavengers of hydroxyl radicals (.OH), and dimethylthiourea has been used to test the involvement of .OH in several animal models of human disease. It is shown that both thiourea and dimethylthiourea are scavengers of HOCl
