物理性质

性状：米色无定形盐结晶粉末。
溶解性：溶于水。

作用与用途

Biochem/physiol Actions 1-4 mg will inhibit 1.0 mg of trypsin with activity of 10,000 BAEE units per mg protein. 2-6 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.
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.
