Summary
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.
