Recombinant Aprotinin
Catalog Number: RTI16-S
CAS: 9087-70-1
Synonyms: Trypsin Inhibitor
Source: Recombinant aprotinin is a genetically engineered protein expressed in E.coli
Storage temperature: Liquid,it should be stored at -20â„?or below;Powder,it should be stored at 2-8â„?
Protein Sequence:The amino acid sequence of recombinant aprotinin is identical to bovine lung derived aprotinin
1.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 co***red to native aprotinin and can replace native trypsin for using in a variety of biotechnological processes.
2.MAIN FEATURES
Source Recombinant E. coli
Appearance Clear, colorless to yellowish liquid
Protein Concentrate �5.0
Specific Activity �3.0 EPU/mg Pro
Absorbance (277nm) �0.8(3 EPU/ml in water)
Purity (HPLC) �5%
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
3.RECOMMEND USAGE
Effective concentration is equimolar with protease. The recommend binding is pHï¼?.0 and it will dissociate at pH <3.0.
4.STABILITY OF STORAGE AND TRANSPORT
�）Stability of storage: Recombinant aprotinin liquid should be stored under -20�in sealed container. It is stable within 6 months at 2-8�
It is no activity loss after 6 times repeated freezing and thawing.
�）Stabilit |
