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


Catalog Number:RSPA05
CAS:91932-65-9
Storage temperature: 2-8℃
Source:Protein A mutant of Staphylococcus aureus , expressed in E. coli

1.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.

PRODUCT ADVANTAGE
1) Non-antibody column purification, the product without any other antibodies such as IgG and other pollution.
2) SPA-25 is our own research and development products, pH tolerance range, can withstand 0.5 M NaOH and 0.5M HCl treatment, no degradation, antibody binding capacity unchanged.
3) The product has a specially designed link for the purification of the column, can be directly used for the preparation of protein A column.
4) Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.
5) High purity: Higher specific activity.Host protein residues is less than the limits of biological products.
6) Lyophilized powder: The product is lyophilized powder and is easy to store and transport.
7) 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: 2015 quality system and GMP guidelines.
8) Complete quality documents: we can provide relevant regular support files in according to customers’ requirement.
