    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

    Source Recombinant E. coli
    Appearance Clear, 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.
