Abstract:
To deal with the complexity of the glycan mixtures released from glycoproteins, an efficient form of micro-column separations, capillary electrochromatography, has been combined with high-performance mass spectrometry (Fourier transform ion cyclotron resonance). Contour plots have been generated from the mixtures of O-linked oligosaccharides originated from bovine mucin and bile salt-stimulated lipase, a large glycoprotein enzyme.
