Carboxypeptidase Enzyme, Animal Origin Free, Carboxypeptidase B, Proteomics Grade
Recombinant 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 | ≥200 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 -20℃. 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: Higher specific activity.Host protein residues is less than the limits of biological products.
Lyophilized powder: The product is lyophilized powder and is easy to store and transport.
Compliance with regulatory requirements: Production equipment and production environment comply with relevant regulatory
requirements, and the production process is in full compliance with NSF ISO 9001: 2015 quality system and GMP guidelines.
Complete quality documents: we can provide relevant regular support files in according to customers’ requirement.
6.PRODUCT USAGE
1) Determination of protein C-terminal basic amino acids such as arginine, lysine and histidine.
2) detection of antibody basic peak.
