Recombinant Aprotinin
Recombinant Aprotinin
Catalog Number: RTI16
Anonym: Trypsin Inhibitor
CAS: 9087-70-1
Source: Expressed in E. Coli
DESCRIPTION
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 >10.0 or <3.0. 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.

UNIT DEFINITION: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.
STORAGE INSTRUCTIONS
Recombinant aprotinin should be stored under -20°C or below in sealed container.It is stable within 24 months.
