AN000068: O-Glycan Profiling using HPAE-PAD Hyphenated with a High-Resolution Accurate Mass (HRAM) Mass Spectrometer
DescriptionWe demonstrate a workflow combining chemical release of O-linked glycans, followed by sample cleanup and analysis by HPAE-PAD hyphenated to a Q Exactive HF Hybrid Quadrupole-Orbitrap MS. A recently introduced Dionex CarboPac PA300-4μm column, enables simultaneous separation of neutral and charged glycans without the need for derivatization. High-resolution MS data and MS/MS spectra with diagnostic fragment ions provide reliable structural annotations of heterogeneous glycans. We applied HPAE-PAD/MS to analyze O-glycan structures released from four different glycoproteins.
