Aprotinin may be stored as lyophilized powder at -20³C for several years without loss of activity.
Sterile filtered aprotinin solutions at pH 5.0-8.0 will be stable for at least three years.
Solutions below pH 4.0 or above pH 9.0 should be used within hours of preparation.
Aprotinin is soluble in water, saline solution, 70% methanol, 70% ethanol, and 50% acetone
store at -20°C
chymotrypsin, plasmin kallikrein, elastase, urokinase, factor XIIa and Protein C.
Aprotinin is a serine protease inhibitor and will inhibit trypsin, anhydrotrypsin, trypsinogen,
