Carbohydrate characterization of an antibody (Lo-BM2) expressed in N. tabacum BY-2 cells showed that the purified Lo-BM2 displays N-glycan homogeneity with a high proportion (>70%) of the complex GnGnXF glycoform. The stable co-expression of a human 尾-1,4-galactosyltransferase targeted ...
Asparagine(N)297-linked glycosylation of immunoglobulin G (IgG) Fc is required for binding to FcγRIIa, IIb, and IIIa, although it is unclear how it contributes. We found the quaternary structure of glycosylated Fc was indistinguishable from aglycosylated Fc, indicating that N-glycosylation does ...
(Asn-X-Ser, Asn-X-Thr or, occasionally, Asn-X-Cys, where X is any amino acid other than proline) is a pre-requisite, though not a guarantee, for N-linkedglycosylation. N-glycosylation can be analyzed by intact mass analysis to determine the overall glycosylation of an antibody, by “...
Open questions What physiological processes are involved in the pathogenesis of liver cancer? What role does N-glycosylation play in the pathogenesis of liver cancer? Does N-glycosylation modification have practical application prospects in the diagnosis and treatment of liver cancer? Introduction Liver c...

we co-labelled DEFs with Flag antibody and an ER-specific fluorescent marker. The Flag antibody can mark both gI and its mutant forms. The results showed that gI single N-glycosylation site mutant did not co-locate with ER in DEFs, but gIN69/78/265A-Flag co-located with ER in DEFs wh...

The severity of COVID-19 has also been associated with higher anti-SARS-CoV-2 IgG and IgA antibody abundance at the time of hospital admission66. Therefore, we sought to correlate IgM glycosylation with the relative abundance of anti-SARS-CoV-2 nucleocapsid (anti-N) immunoglobulins (see Supple...
The role of IgG N-glycans in the modulation of its effector functions has been well recognized49,50,51,52. One of the most studied examples is the addition of core fucose to the Fc fragment Asn297 N-glycosylation site that decreases antibody-dependent cell-mediated cytotoxicity (ADCC) up to...
