Glycan analysis was also executed by enzymatically releasing the glycan moiety in solution followed by separa-tion on a graphitized carbon column and accurate mass determination on the HPLC-Chip coupled to a Q-TOF. Site-specific characterization of glycoform heterogeneity currently requires glycan structure assignment and glycopeptide quantification in two independent experiments. We present here a new method combining multiple reaction monitoring mass spectrometry with energy-resolved structural analysis, which we termed “energy-resolved oxonium ion monitoring”. The glycopeptides were further analyzed by high-resolution LC-MS/MS, using a glycan oxonium ion product-dependent higher-energy collisional dissociation (HCD) triggered collision-induced dissociation (CID) program.
