Biochem/physiol Actions

≤10 mg will inhibit 1.0 mg of trypsin with activity of 10,000 BAEE units per mg protein. ≤10 mg will inhibit approx. 1.0 mg of ·α-chymotrypsin with activity of 40-50 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.

Caution

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.

Preparation Note

Chromatographically prepared and partially purified.
