recombinant aprotinin recombinant trypsin inhibitor and Aprotinin
Recombinant Aprotinin / Aprotinin / RTI / rTI / Trypsin Inhibitor
DESCRIPTION
Recombinant Aprotinin
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 is equimolar with protease.
RECOMBINANT, ANIMAL COMPONENTS FREE
Recombinant aprotinin is expressed in E. Coli, and then purified with HPLC. It contains no animal-derived components. This is a recombinant form of the native, bovine-
sequence 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 μmole 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.
