Sequencing Grade Carboxypeptidase B
Catalog Number:SRCPB01
CAS:9025-24-5
EC:3.4.17.2
Storage temperature: 2-8â„?
Source: Sequencing grade recombinant carboxypeptidase B is a genetically engineered protein expressed in E.coli
Protein Sequence:The amino acid sequence of recombinant carboxypeptidase B is identical to rat carboxypeptidase B
1.DESCRIPTION
Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and histidine from the C-terminal end of polypeptides. The molecular weight is 33.8kD, pI is 6.0 and the optimum pH is 7.5-9.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA.
2. MAIN FEATURES
Source Recombinant E. coli
Appearance White or off white, or yellowish powder
Specific activity �00 units/mg pro.
SDS-PAGE Single major band
Molecular Weight(SDS-PAGE) 33.8±3.4 kDa
Purity(HPLC) �95%
3.RECOMMEND USAGE
Prepare 1-10mg/ml carboxypeptidase B with sterile water or 25mM Tris-HCl pH 7.65. The ratio to aimed protein is 1:50 to 1:1000 (w/w), the optimum pH is pH 7.5-9.0.
4.STABILITY OF STORAGE AND TRANSPORT
�）Stability of storage: Sequencing grade carboxypeptidase B lyophilized should be stored under 2-8�in sealed container. It is stable within 24 months.
After dissolved with sterile water or 25mM Tris-HCl, it should be stored under -20â„? Avoid repeated freezing and thawing.
�）Stability of transport: The product is stable by blue ice insulation transport.
5.PRODUCT ADVANTAGE
�）Sequence grade recombinant protein: high specificity,good stability.
�）Animal origin free: Sequencing grade carboxypeptidase B 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: Highe |
