Recombinant Protein A
Storage temperature: 2-8℃
Source:Protein A mutant of Staphylococcus aureus , expressed in E. coli
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.
