Protein A/G/L/AG

The four proteins bind almost exclusively with the IgG class of antibodies, but their binding properties differ among species and subclasses of IgG.Protein A binds with IgG of rabbit, pig, dog, and cat. Protein G better binds with mouse and human IgG. Protein A/G is a fusion recombinant protein that includes binding domains of both Protein A and G. Protein L binds to light chain of all classes of IgG, IgM, IgA, IgE, and IgD.
