WebOct 12, 2024 · High mannose is an early product of the N -glycan pathway, predominantly seen as an intracellular epitope ( 12 ). These lectins showed a statistically significant ∼47 to 50% increase in binding to lung tissue from severely infected animals compared to uninfected controls. WebOne of the most common, and possibly the best-studied, type of protein modification in antibody molecules is glycosylation. The highly conserved residue Asn 297 present in the CH2 domain of each heavy chain provides 2 potential N-glycosylation sites in each antibody molecule, resulting in a wide variety of glycosylation patterns.
