      Recombinant Carboxypeptidase B

     

    Catalog Number:RCPB01

    CAS: 9025-24-5
    EC: 3.4.17.2

    Storage temperature: 2-8℃

    Source: 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. YaxinBio has cloned rat carboxypeptidase B gene into  E.coli for expression with equivalent properties compared to animal original carboxypeptidase B .Recombinant carboxypeptidase B can replace native carboxypeptidase B for using in a variety of biotechnological processes.

    4.STABILITY OF STORAGE AND TRANSPORT

    Stability of storage: Recombinant 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℃. 

    It is no activity loss after 10 times repeated freezing and thawing.

    Stability of transport: The product is stable by blue ice insulation transport.

     

    5.PRODUCT ADVANTAGE

    ① Animal origin free: Recombinant carboxypeptidase B is no exogenous virus contamination,and any animal origin material is not used in the production process.

    ② Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.

    ③ High purity: Higher specific activity.No other contaminating proteases such as chymotrypsin and carboxypeptidase A.Host protein residues is less than the limits of biological products.

    ④ Lyophilized powder: The product is lyophilized powder and is convenient to store and transport.

    ⑤ 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: 2008 quality system and GMP guidelines.

    ⑥ Complete quality documents: we can provide relevant regular support files in according to customers’ requirement.
