Specific enrichment methods for glycoproteome research.

Glycosylation is, by far, one of the most common and important post-translational modifications and becomes a target for proteomic research. A key challenge in glycoproteome research is the development of fast and effective enrichment strategies for high-throughput glycosylation analysis. Different kinds of glycan-capturing anchors have been developed and successfully applied to glyco-specific enrichment in large-scale glycosylation identification in the past few years. In this paper, we highlight several examples on various types of enrichment methods that have been utilized to specifically capture glycopeptides/glycoproteins for subsequent mass spectrometric analysis.
