Protein G binds to all IgG subclasses from human species, mice, and rats. It also binds to IgG from guinea pig, rabbit, goat, cow, sheep, and horse. Protein G exhibits a broader range of binding to IgG subclasses than does staphylococcal protein A. Some of … Continue reading “Recombinant Streptococcal Protein G (r-SPG)”
