High-throughput and high-sensitivity nano-LC/MS and MS/MS for O-glycan profiling

Methods Mol Biol. 2009:534:117-31. doi: 10.1007/978-1-59745-022-5_9.

Abstract

Sensitive and fast methods for the profiling of biologically important molecules are highly demanded. Mucins are densely O-glycosylated glycoproteins found at mucosal surfaces and are of great medical interest. Here we describe sensitive methods for the analysis of O-glycans from mucins using gel electrophoresis, and chromatography by nanoLC on graphite columns and structural analysis by electrospray mass spectrometry on a linear trap mass spectrometer.
