Recombinant Aprotinin, Expressed in E.coli, BPTI Inhibit Kallikrein, CAS 9087-70-1


Recombinant Aprotinin


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 <3.0. Effective concentration is equimolar with protease. YaxinBio recombinant aprotinin is a genetically engineered protein expressed in E.coli and purified by multi-column.The amino acid sequence of recombinant trypsin is identical to bovine lung derived aprotinin,with equivalent properties compared to native aprotinin and can replace native trypsin for using in a variety of biotechnological processes.


MAIN FEATURES

SourceRecombinant E. coli
AppearanceClear, colorless to yellowish liquid
Protein Concentrate≥ 5.0
Specific Activity (EPU /mg protein)≥ 3.0
Absorbance (277nm)≤ 0.8(3 EPU/ml in water)
Purity (HPLC)≥95%

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


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.
