Recombinant protein A, Pierce™
Protein Purification Protein Purification Reagents
Pierce™ Recombinant Protein A is useful as the basis for preparing various kinds of probes or affinity media for detection or purification of rabbit and human antibodies, especially IgG isotypes, in immunoassays and antibody purification protocols.

  • Contains four Fc-binding domains per protein
  • More efficient than Protein G for polyclonal IgG from rabbit, pig, dog and cat serum
  • Less efficient than Protein G for mouse IgG1, human IgG3 and rat, goat and cow antibodies

Protein A is a cell wall component produced by several strains of Staphylococcus aureus that consists of a single polypeptide chain and contains little or no carbohydrate. Recombinant Protein A is produced in E. coli and functions essentially the same as native Protein A. The Protein A molecule contains four high-affinity binding sites capable of interacting with the Fc region from IgG of several species including human and rabbit. Optimal binding occurs at pH 8,2, although binding is also effective at neutral or physiological conditions (pH 7,0 to 7,6).
