蛋白酶抑制剂 Aprotinin from bovine lung Descriptions

Preparation Note Contains no animal-derived components or impurities, and is manufactured by transient expression of the aprotinin message in RNA (+)-strand tobacco mosaic virus vectors propagated in non-transgenic Nicotiana plants.

Unit Definition One trypsin inhibitor unit (TIU) will decrease the activity of 2 trypsin units by 50% where one trypsin unit will hydrolyze 1.0 μmole of N-α-benzoyl-DL-arginine p-nitroanilide (BAPNA) per min at pH 7.8 at 25 °C.

Biochem/physiol Actions Serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Effective concentration equimolar with protease. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or <3.
