AN73063: Improved Profiling of Sialylated N-Linked Glycans by Ion Chromatography-Orbitrap Mass Spectrometry
Description
The methods proposed here use a Thermo Scientific™ Dionex™ CarboPac™ PA200 column for glycan separation by HPAE. After the separation the glycans pass through a desalting device and in to the mass spectrometer. Fragmentation of glycans in the negative mode by higher-energy collisional dissociation (HCD) provides information-rich MS2 spectra which enables glycan structure annotation. This allowed correlation of glycan structure with observed elution behavior. Here we show that in some cases, changed elution conditions can be used to resolve different glycan structures.| Market: | BioPharma |
