Mass Spectrometry of Glycoproteins: Methods and Protocols

Glycosylation is the most abundant post-translational modification of proteins. Estimates vary widely, but a common assessment is that upwards of 50% of eukaryotic proteins are modified by some type of glycan. In expert researchers in the field detail many of the methods that are now commonly used for glycoproteomics. These methods and techniques include robust sample preparation techniques; advanced chromatographic strategies for improving dynamic range; state-of-the-art mass spectrometry instrumentation and associated ionization and fragmentation methods; and informatics tools used for identifying glycoproteins and characterizing the associated glycans. Written in the highly successful series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory prools, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, is an essential resource for those who work at the interface of glycobiology and mass spectrometry.
