Protein A for tolerance to Acid and Alkali Preparation of
Recombinant Protein A Column
Recombinant Protein A
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.
STABILITY OF STORAGE AND TRANSPORT
Stability of storage: Recombinant protein A lyophilized should be
stored under 2-8℃ in sealed container.
It is stable within 24 months.When gluing even with PBS (pH7.4)
dissolved,it is now with the current use.
After dissolved with pure water, it should be stored under -20℃.
Stability of transport: The product is stable by blue ice
E0.1% at 275nm=0.17-0.23
No DNA or RNA detected
No Triton contaminant.
