Convenient pre-separation method depends on negative charges suitable for glycan sequencing analysis

Biosci Biotechnol Biochem. 2024 May 22;88(6):637-638. doi: 10.1093/bbb/zbae030.

Abstract

For precise structural analysis of complex glycans, it is necessary to fractionate glycans based on acidity prior to liquid chromatography-mass spectrometry analysis. Conventional fractionation using high-performance liquid chromatography is time consuming and not high throughput. Therefore, we developed a rapid method for the fractionation using a small cartridge column. This enables rapid multi-sample processing for glycan sequencing.

Keywords: anion exchange; glycan sequencing; mass spectrometry; sialic acid.
