Gammabind G Sepharose^™

Recombinant GammaBind is an affinity medium for laboratory scale antibody purification. Binds to all IgG subclasses from human, mouse, and rat; binds total IgG from guinea pig, rabbit, goat, cow, sheep, and horse.

GammaBind G Sepharose^™ is GammaBind G, Type 2, covalently immobilized to Sepharose^™ 4B by the cyanogen bromide method. GammaBind G, Type 2, a recombinant form of streptococcal Protein G, binds to the Fc region of IgG from a variety of mammalian species. GammaBind G Sepharose^™ may be used to analyze and purify classes, subclasses and fragments of immunoglobulins from any biological fluid or cell culture medium.

GammaBind G Sepharose^™ may be used to analyze and purify classes, subclasses and fragments of immunoglobulins from any biological fluid or cell culture medium. Since only the Fc region is involved in binding, the Fab region is still available for binding antigen. Hence, GammaBind G Sepharose^™ is extremely useful for isolation of immune complexes. GammaBind G will not cross-react with other serum proteins such as IgM, IgE, IgA or transferrin.

pH below 3 is sometimes required to elute strongly bound IgG species. However, protein ligands may hydrolyze at very low pH.

The potential applications of GammaBind G Sepharose^™ include practically all of the current and projected applications of Protein A Sepharose. However, GammaBind G and Protein A have different IgG binding specificities, depending on the origin of the IgG. Compared to Protein A, GammaBind G binds more strongly to mouse and rat monoclonal IgG and to IgG from goat, sheep, horse, cow, human, rabbit and other mammalian species.
