Abstract:N-Linked glycosylation on IgG has a profound impact on antibody functions. The relationship between the N-glycan structure and the binding affinity of FcγRIIIa, relating to antibody-dependent cell-mediated cytotoxicity (ADCC) activity, is important for the efficient development of a therapeutic antibody. Here, we report an influence of the N-glycan structure of IgGs, Fc fragments, and antibody-drug conjugates (ADCs) on FcγRIIIa affinity column chromatography. We compared the retention time of several IgGs with… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
