Proteins A and G bind almost exclusively with the IgG class of antibodies, but their binding properties differ among species and subclasses of IgG. Protein A is generally preferred for rabbit, pig, dog and cat IgG. Protein G has better binding capacity for a broader range of mouse and human IgG subclasses (IgG1, IgG2, etc.). These recombinant proteins are covalently immobilized to crosslinked agarose beads.

OriGene’s Protein A Sepharose® and Protein G Sepharose® have been used to purify more than 4,000 TrueMAB™ antibodies.
