The IgG Asn-297 N-glycan heterogeneity. Panel (A) major types of N-glycosylation observed in IgG. Panel (B) detail of complex type glycosylation with percentage of circulating IgG containing either fucose or bisecting N-Acetylglucosamine. The orange circle indicates the core structure. The blue broken lines and text indicate the heterogeneity of complex N-glycans, carrying either no Gal (G0), 1-2 Gal (G1/2), 1-2 Sialic acids (S1/2), with (F) or without core α-1,6-fucose.
