WebbProtein A does not bind all subclasses of IgG, e.g., human IgG 3, mouse IgG 3, sheep IgG 1, and some subclasses bind only weakly, e.g., mouse IgG 1. For some species, IgG does not bind to protein A at all, e.g., rat, chicken, goat, and some MAbs show abnormal affinity for … Webb24 maj 2024 · A purification matrix based on the ZCa protein A–derived domain displays calcium-dependent binding of IgG and elution under mild conditions (10). We investigated using commercially available CaptureSelect CH1-XL affinity resin from Thermo Fisher Scientific for purification of bispecific antibody CD3-TAA.

WebbProtein G binding is optimal at pH 4–5, whereas the optimum for protein A binding is at pH 8.0. All four human IgG subclasses interact with protein G with high affinity ( Table 22 ). Protein G binds to the Fc as well as to the Fab portions. However, the interactions between protein G and Fab are much weaker than the interaction with Fc.
