Protein A and G are popular choices for Immunoprecipitation and antibody purification, because they are both stable and target selective. IgG class antibodies from multiple species bind to protein A and/or G, allowing antibody to be captured on protein-agarose microspheres. Protein A and G bind IgG subtypes with varying affinities, determined by species and the properties of the heavy chain. Protein A/G Magnetic Beads provides a simple, rapid, and efficient method for Immunoprecipitation and Co-Immunoprecipitation.
