Analysis Note Another commonly used unit of activity is the KIU (Kallikrein Inhibitor Unit). 1 TIU ∼ 1,300 KIU. 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 Aprotinin is a competitive serine protease inhibitor that inhibits trypsin, chymotrypsin, kallikrein and plasmin. Aprotinin forms stable complexes with and blocks the active sites of enzymes. Binding is reversible with most aprotinin-protease complexes dissociating at pH >10 or <3. Effective concentration equimolar with protease. General description Aprotinin is a protein consisting of 58 amino acids, arranged in a single polypeptide chain that is crosslinked by three disulfide bridges. 性质 form lyophilized powder mol wt mol wt ~6,500 solubility H2O: >10 mg/mL storage temp. 2-8°C 安全性 Personal Protective Equipment Eyeshields, Gloves, type N95 (US), type P1 (EN143) respirator filter Safety Statements 22 WGK Germany 1 RTECS YN5080000
