Recombinant Proteins  >  Protein A - Labeled (HiLyte™ & Biotin) and Unlabeled  >>  Protein A, recombinant

Product Name Protein A, recombinant
Size 100 mg
Catalog # AS-72233-100
US$ $378

Protein A is a non-glycosylated cell wall protein of Staphylococcus aureus that can bind the Fc part of immunoglobulin molecule of different species with strong affinity (1-4). Protein A consists of five IgG binding domains (A, B, C, D, and E), each approximately 60 amino acids long with no cysteines present and two S. aureus cell membrane binding domains, X and M (3).

AnaSpec's recombinant Protein A consists of only IgG binding domains and was expressed using a recombinant bacterial expression system. Its apparent molecular weight is approximately 30,000 Da compared to 42,000 Da for the native Protein A that is found in Staphylococcus aureus. Recombinant Protein A can be used for immunoprecipitation, antibodies purification, and assay development.
