Recombinant Protein G, His-tagged

Protein G is an immunoglobulin-binding protein expressed ingroup C and G Streptococcal bacteria much like Protein A but with differingspecificities. It is a 65-kDa (G148 protein G) and a 58 kDa (C40 protein G)cell surface protein that has found application in purifying antibodiesthrough its binding to the Fc region. The native molecule also binds albumin,however, because serum albumin is a major contaminant of antibody sources,the albumin binding site has been removed from this recombinant form ofProtein G.
