- Additional Names:
- Immunoglobulin G-binding protein A||IgG-binding protein A||Staphylococcal protein A||SPA.
- Extra Details:
- Source : Escherichia Coli. SPA Recombinant produced in E.Coli is a single non-glycosylated polypeptide chain fused with 6— His tag at C-terminus. SPA is comprised of 5 IgG-binding domains E-D-A-B-C aligned in series containing 306 amino acids and having a molecular mass of 34.7kDa containing little or no carbohydrate. Cell wall binding region; cell membrane binding region and albumin binding region were removed to ensure the highest specific IgG binding. Protein A is a cell wall component produced by several strains of Staphylococcus aureus. The recombinant Protein A is genetically engineered protein and holds 5 IgG-binding regions of protein A. Recombinant Protein A functions basically the same as native Protein A and is perfect for purification of polyclonal or monoclonal IgG antibodies. Protein A binds to human IgG1; IgG2 and IgG4; mouse IgG2a; IgG2b and IgG3 and rat IgG2c. Protein A also binds to total IgG from rabbit; pig; dog; cat; and guinea pig.
- Purification:
- Greater than 97.0% as determined by: (a) Analysis by HPLC.(b) Analysis by SDS-PAGE.
- Shipping Conditions:
- Blue Ice
- Storage Conditions:
- Lyophilized SPA although stable at room temperature for 3 weeks; should be stored desiccated below -18[o]C. Upon reconstitution SPA should be stored at 4[o]C between 2-7 days and for future use below -18[o]C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
