Recombinant S.aureus Immunoglobulin G Binding Protein A

Cat. No.: spa-515S
Product Overview: Recombinant Staphylococcus aureus Protein A was expressed inE.coliand purified by using conventional chromatography. MW =48.1 kDa (434aa).
Description: Protein Ais a 40-60kDasurfaceproteinoriginally found in the cell wall of thebacteriaStaphylococcus aureus. It binds with high affinity to human IgG1 and IgG2 as well as mouse IgG2a and IgG2b. Protein A binds with moderate affinity to humanIgM,IgAandIgEas well as to mouse IgG3 and IgG1. Due to its affinity for the Fc region of many mammalian immunoglobulins, protein A is considered a universal reagent in biochemistry and immunology.
Source: E.coli.
