Frequently Asked QuestionsLive Chat andFrequently Asked Questions are available for this Product.ApplicationAprotinin is largely used as an inhibitor of trypsin.Preparation NoteThis product is a lyophilized powder with activity of 3-8 TIU/mg of solid powder. Aprotinin is freely soluble in water (>10 mg/mL) and in aqueous buffers of low ionic strengths. Dilute solutions tend to be less stable than concentrated ones, though solution stability also depends on pH. Aprotinin is relatively stable against denaturation - only thermolysin has been found capable of degrading it at 60-80°C. Sterilizaiton of Aprotinin can be achieved through filtration by a 0.2 μm filter.Unit DefinitionOne Trypsin Inhibitor Unit (TIU) will decrease the activity of two trypsin units by 50%, where one trypsin unit will hydrolyze 1.0 μmole of Nalpha-benzoyl-DL-arginin​e p-nitroanilide per minute at pH 7.8 and 25°C. Another commonly used unit is the KIU, with 1 TIU = 1,300 KIU.Biochem/physiol Actions可以抑制胰蛋白酶、胰凝乳蛋白酶、激肽释放酶以及纤溶​酶的丝氨酸蛋白酶抑制剂。
