Recombinant protein A Colloidal Gold and Radioactive Markers EC297-246-6


Recombinant Protein A


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.

Shanghai Yaxin Biotechnology Co.,Ltd.

       Shanghai Yaxin Biotechnology company was founded in 2008,which is a high-tech enterprise that focuses on researching and producing the recombinant proteins.YaxinBio is the first and only a company on researching and producing the recombinant carboxypeptidase B and recombinant trypsin.Animal original free enzymes are specially used in the human recombinant insulin production,and exporting abroad.

       Recombinant trypsin is used in the cell culturing process,which conforms to the 2014 USP on the usage of trypsin in the cell culture.Animal original free is very important for the production of antibody and vaccine.Usage of recombinat trypsin fundamentally solves the problem of animal original virus contamination in the human recombinant insulin production.

       YaxinBio insists on “scientific and technological innovation”,has developed with independent intellectual property rights of the products.YaxinBio obtained the support of Chinese ministry of science and technology and Shanghai innovation fund project in 2010; Recombinant trypsin,recombinant carboxypeptidase B and recombinant protein A won the Shanghai high-tech achievement transformation project in Sep.2013.
