||Protein A is a wall-anchored protein of S. aureus that binds the Fc portion of immunoglobulin G (IgG) and coats the surface of the bacterium with IgG molecules that are in the incorrect orientation to be recognized by the neutrophil Fc receptor.
||Recombinant Protein A expressed in E.Coli is a non-glycosylated, Polypeptide chain having a molecular mass of 30 kDa. Theoretical pI is 5.10. Recombinant Staphylococcal Protein A is purified using our unique purification methods.
||>95.0% as determined by RP-HPLC.
||The recombinant Protein A was lyophilized from 5 mM PB, pH7.4.
||For Research Use Only
