This article describes the analysis of fluorescently labelled N-glycans released from proteins by liquid chromatography–mass spectrometry (LC–MS). The column for this separation used mixed-mode surface chemistry that combines weak anion-exchange and hydrophilic interaction liquid chromatography (HILIC) retention mechanisms for high-resolution and high-throughput analysis of glycans. This combination of modes offers unique selectivity that provides separation of glycans based on charge, size, and polarity. MS and MS–MS analyses were performed using a hybrid quadrupole-orbitrap-based mass spectrometer in negative ion mode to provide detailed structural information of N-glycans released from proteins.
