N-linked glycan mass
WebN-linked glycosylation, is the attachment of an oligosaccharide, a carbohydrate consisting of several sugar molecules, sometimes also referred to as glycan, to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein ), in a process called N-glycosylation, studied in biochemistry.

WebN-linked glycosylation, modification, and degradation are involved in a wide variety of processes in all organisms from archaea to eukaryotes. It is the most common covalent … 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.
