Recombinant Human Chymotrypsin
Catalog Number:RCT10
CAS: 9004-07-3
EC: 3.4.21.1
Storage temperature: 2-8â„?
Source: Recombinant huamn chymotrypsin is a genetically engineered protein expressed in E.coli
Protein Sequence:The amino acid sequence of recombinant human chymotrypsin is identical to human chymotrypsin
1.DESCRIPTION
Chymotrypsin is a recombinant serine endopeptidase expressed in E.coli, the gene sequence is the same as human chymotrypsin. Recombinant chymotrypsin hydrolyzes at the carboxyl side of aromatic amino acids residues: Tyr, Phe and Trp. Cleavage may also be observed, but at a lower rate, at Leu and Met. Chymotrypsin activity is optimal in pH 7.0�.0.
2.MAIN FEATURES
Source Recombinant E. coli
Appearance White or off white powder
Specific activity �000 USP units/mg pro.
SDS-PAGE Single major band
SDS-PAGE (MW) 24.0±2.4 kDa
UNIT DEFINITION: One unit will hydrolyze 1.0 μmol of N-alpha-acetyl-L-tyrosine ethyl ester(ATEE) per min at pH 7.0 at 25 °C.
3.RECOMMEND USAGE
Prepare 1-10mg/ml recombinant human chymotrypsin with 1mM HCl.The ratio to aimed protein is 1:50 to 1:1000 (w/w).The optimum pH is pH7.0-9.0.
4.STABILITY OF STORAGE AND TRANSPORT
�）Stability of storage: Recombinant human chymotrypsin lyophilized should be stored under 2-8�in sealed container. It is stable within 24 months.After dissolved with 1mM HCl , it should be stored under -20� Avoid repeated freezing and thawing.
�）Stability of transport: The product is stable by blue ice insulation transport.
5.PRODUCT ADVANTAGE
�）Animal origin free: Recombinant human chymotrypsin is no exogenous virus contamination,and any animal origin material is not used in the production process.
�）Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.
�）High purity: Higher specific activity.Host protein residues is less than the limits of biological products.
�）Lyophil |
