Recombinant protein A

Recombinant  protein A
Product Description

DESCRIPTION
Protein A is a membrane protein of Staphylococcus aureus and can specifically bind to antibodies. Protein A affinity chromatography columns have become widely used as affinity columns for purified antibodies from ascites, serum and cell culture isolated or purified extracts of antibodies from different subtypes of mammals or genetically engineered recombinant proteins containing antibody Fc fragments. alkali protein A is our company independent research and development production, with independent intellectual property rights. Recombinant protein A is expressed by E. coli and purified by chromatography to give a purity of 95% or more. The purification process does not use antibody column affinity chromatography to avoid the possibility of incorporation of unrelated IgG in the product.

APPLICATION:
The C-terminus of the recombinant protein A contains cysteine which can be coupled to the solid separation medium for purification of the monoclonal antibody or polyclonal antibody. Recombinant protein A can be conjugated to a variety of reporter molecules (fluorescent dyes, enzyme labels, biotin, colloidal gold, radioactive labels, etc.) without affecting its binding to the antibody. These conjugated protein A derivatives can be used for antibody detection of Western-blot, ELISA, immunohistochemistry.

    Animal origin free
    Recombinant carboxypeptidase B eliminates the risk of viruses, or other potential adventitious agents found in animal derived carboxypepitdase B. Which belong to the AOF level 3 products.

    Stable
    A sterile recombinant carboxypeptidase B lyophilized powder eliminates the contamination opportunity and decreases the chance of activity loss in the process of transport and storage. Convenient for transport and store.

    High purity

    1)Recombinant carboxypeptidase B provides increased specificity and eliminates contaminating activities found in lower purity enzymes
    2)No other proteases contaminated such as chymotrypsin, carboxypeptidase A, and the content of recombinant trypsin less than 10ppm.
    3)One single main band at 35kD by SDS-PAGE.
