We have found the information on alpha-1-antitrypsin in a reference book:The Plasma Proteins, F.W. Putnam, ed, volume 2, chapter 4, Table II.The alpha-1-antitrypsin is 12 percent carbohydrate, citing K. Heide and H.G. Schwick, Chemistry and Significance of the Carbohydrate Moieties of Human Serum Glycoproteins, Angew. Chem., Int. Ed. Eng., 12, 721-733 (1973).The table also gives information on the percentage of each type of monosaccharide that is present.

Actions biochimiques/physiologiques
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.
Attention
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.
Notes préparatoires
Chromatographically prepared and partially purified.
