Protein G - Wikipedia
网页Protein G is an immunoglobulin-binding protein expressed in group C and G streptococcal bacteria much like protein A but with differing binding specificities. It is a ~60-kDA (65 kDA for strain G148 and 58 kDa for strain C40) [1] cell surface protein that has found application in purifying antibodies through its binding to the Fab and Fc region.
