The method includes enzymatic release and labeling of N-glycans with a signal-enhancing tag, LC-MS data collection, and data interpretation. Using the given protocol, up to 24 glycan samples can be prepared within 1 h, while the LC-FLR/MS data can be collected and analyzed using an established data processing method in a semi-automated manner.
