Hilic n-glycan
WebAug 1, 2008 · We here describe a 96 well plate-based high-throughput procedure for the rapid preparation of 2-aminobenzoic acid (2-AA) labeled N-glycans from 10 microL of human plasma. During this procedure, N-glycans are released from glycoproteins and subsequently labeled with 2-AA without prior purification. WebHydrophilic interaction chromatography (or hydrophilic interaction liquid chromatography, HILIC) is a variant of normal phase liquid chromatography that partly overlaps with other chromatographic applications such as ion chromatography and reversed phase liquid chromatography.

WebTo address these shortcomings, we have developed an N -glycan labeling reagent that provides enhanced fluorescence response and MS sensitivity for glycan detection and have also simplified the process of preparing a sample for analysis. The developed labeling reagent rapidly reacts with glycosylamines upon their release from glycoproteins. WebThe N-linked glycans released from glyco proteins were extracted using the 96-well, MassPREP HILIC µElution Plate attached to a vacuum manifold. Use of this SPE device involves an initial wash and equilibration of the sample well (s), sample loading, sample well washing to remove undesired products, and final elution of the isolated glycans.
WebGlycan Analysis Services - Level 2 This module is an extension of the Level 1 HILIC profiling work to gain more detailed information on the glycan structures and their relative proportions. This can be achieved by Exoglycosidase digestion followed by HILIC-UPLC and/or by HILIC-UPLC-FLR-ESI-MS/MS analyses.
