Abstract
Glycans having a branched structure are labeled with a labeling agent, such as 2-aminobenzoic acid, having one site that is easily negatively charged. At this time, reduction which is usually performed in labeling by reduction amination is not performed. A sample for mass spectrometry containing the labeled form of glycans thus obtained is prepared, and is subjected to MS/MS analysis in negative ion mode. In the MS/MS spectra obtained by the MS/MS analysis, peaks of E ions, D ions and the like which reflect the branched structure clearly appear. As a result, structural analysis of an entirety of the glycan including the branched structure can be easily performed.
