생화학적/생리학적 작용
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.
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.
주의사항
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.
제조 메모

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

The objective of this study was to investigate the uterine uptake of plasma alpha 1-proteinase inhibitor (53,000 Da) and alpha 2-macroglobulin (725,000 Da) from the blood during implantation in the mouse using isotopic methods. The uterine uptake of albumin (67,000

Ascorbic acid, at physiological concentrations, can scavenge the myeloperoxidase-derived oxidant hypochlorous acid at rates sufficient to protect alpha 1-antiprotease against inactivation by this molecule. The rapid depletion of ascorbic acid at sites of inflammation, as in the inflamed rheumatoid joint

Carnosine, homocarnosine and anserine have been proposed to act as antioxidants in vivo. Our studies show that all three compounds are good scavengers of the hydroxyl radical (.OH) but that none of them can react with superoxide radical, hydrogen peroxide
