High throughput plasma N-glycome profiling using multiplexed labelling and UPLC with fluorescence detection

A rapid glycomic profiling method is described wherein N-glycans from plasma samples individually labelled with aniline, 2-amino-benzamide and 2-aminoacridone are mixed, co-injected and separated in the same HILIC-fluorescence run. Transfer of the multiplexed method to UPLC-fluorescence permits an increase in sample throughput from 24 to 864 plasma samples per day.
