A sample preparation workflow to facilitate deep N-glycomics analysis of human serum by capillary electrophoresis with laser induced fluorescence (CE-LIF) detection accommodates the higher sample concentration requirement of electrospray ionization mass spectrometry connected to capillary electrophoresis (CE-ESI-MS). A temperature gradient denaturing protocol is applied on amine functionalized magnetic bead partitioned glycoproteins to avoid precipitation. This also results in the free sugar content of the serum being significantly decreased which allows PNGase F mediated release of the N-linked carbohydrates. The liberated oligosaccharides were tagged with aminopyrene-trisulfonate, utilizing a modified evaporative labeling protocol. This workflow provides appropriate amounts of material for example for use in CE-ESI-MS analysis in negative ionization mode.
