WebHILIC, or hydrophilic interaction chromatography, is a normal phase chromatography. In some ways the opposite of the more familiar reversed phase chromatography, with gradients starting at high organic solvent content rather than high aqueous content. WebN-linked glycans are easily released from proteins using PNGaseF. Upon release, glycans do not contain a chromophore so they must be derivatized prior to analysis with a suitable label which provides fluoresce and mass spectrometric response. The use of 2-AB is the most common label for HILIC-FLR-MS analysis and was selected for this study.
