Recombinant Aprotinin EC 184.108.40.206 Aprotinin from Bovine Lung 3 EPU/mg pro
Anonym: Trypsin Inhibitor
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 and dissociating at pH >10 or <3. Effective concentration is equimolar with protease.
Recombinant Animal Components Free
Recombinant aprotinin is expressed in E. Coli, and purified by HPLC. It contains no animal-derived components. This is a recombinant form of bovine lung aprotinin, which is traditionally isolated from bovine lung by methods involving fractional precipitation, gel filtration, and ion exchange chromatography.
One trypsin inhibitor unit (EPU) will decrease the activity of 2 trypsin units by 50% where one trypsin unit will hydrolyze 1.0 μmol of N-benzoyl-L-arginineethyl ether(BAEE) per sec at pH 7.6 at 25 °C.A conversion factor for Aprotinin is: 1 EPU= 1 USP Aprotinin Unit = 1800 KIU.
Recombinant aprotinin should be stored under -20°C or below in sealed container.It is stable within 24 months.
