We demonstrated that with enhanced detection sensitivity, IP-HILIC-MS can confidently identify an increased number of site-specific N-linked glycans for IgG1, and IgG4 mAbs as well as an Fc-domain fusion protein (containing five N-glycosylation sites) through MS/MS-based search in the data-dependent acquisition mode, meanwhile, achieve comparable quantitative results compared with the traditional methods. We also demonstrated that IP-HILIC-MS can be used to identify low-level O-glycosylation and non-consensus N-glycosylation on mAbs w
