Summary

Automatically generated

In order to comprehensively explore the diversity of O-linked glycans, a new procedure for in-gel reductive β-elimination, combined with permethylation and a rapid phase-partition method, is applied to the analysis of O-linked glycans directly released from glycoproteins resolved by SDS-PAGE and amenable to subsequent glycomic analysis by mass spectrometry.
