Choice of host cell line is essential for the functional glycosylation of the fragment crystallizable (Fc) region of human IgG1 inhibitors of influenza B viruses
Abstract:Antibodies are glycoproteins that carry a conserved N-linked carbohydrate attached to the Fc, whose presence and fine structure profoundly impacts on their in vivo immunogenicity, pharmacokinetics and functional attributes. The host cell line used to produce IgG has a major impact on this glycosylation, as different systems express different glycosylation enzymes and transporters that contribute to the specificity and heterogeneity of the final IgG-Fc glycosylation profile. Here we compare two panels of glycan… Show more
