Glycosylation is a common post-translational modification (PTM) that plays a critical role in antibody effector functions. Comprehensive characterization of N- and O-linked glycosylation in protein therapeutics is essential for ensuring drug safety and efficacy.
Accurate determination of glycosylation sites using traditional collision-based MS/MS approaches is extremely challenging.
