WebbHiTrap Protein G HP columns are prepacked with Protein G Sepharose High Performance resin. This protein G affinity resin is a good first choice for general-purpose capture of antibodies at laboratory scale, because it binds to a broader range of IgG from eukaryotic species and also binds to more subclasses of IgG than protein A-based resins do. WebbThe proteins are widely used as affinity matrices for purification of IgG. For both proteins, the major binding site in IgG is located in the Fc part of the antibody at the CH2–CH3 …

WebbIn general, protein G presents higher affinity for IgGs than protein A. Protein G can also bind IgGs from a wider variety of species. In addition, the affinity of protein A for various IgG subclasses, especially from mouse and human, varies more than for protein G. Protein A can therefore be used to prepare isotypically pure IgG from some species. WebbProtein G (derived from groups C and G Streptococci) also binds to IgG Fc with some differences in species specificity from protein A. Protein G binds to IgG of most species, including rat and goat, and recognizes most subclasses (including human IgG 3 and mouse IgG 1 ), but has a lower binding capacity.
