recombinant aprotinin 9000KIU/mg pro,Aprotinin in E.coli BPTI
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.
1. Source E. Coli
2. Purified by HPLC
3. Physical form Liquid in 0.1 M NaCl or White lyophilized powder
4. Specific activity ≥ 5 EPU/mg pro.
5. Purity ≥ 98% by SDS-PAGE
6. Contaminant activity No any other protease contaminant.
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.
