The labeling by amino acids and peptides was investigated for sensitive and fast analyses of oligosaccharides and N-linked glycans by capillary electrophoresis-mass spectrometry (CE-MS). Peptide tags with a various number of histidine residues were tested for maltooligosaccharide labeling in order to investigatethe effect of the size of labels and a number of charges on CE-MS analysis. Nevertheless, the reductive amination labeling of N-linked glycans by a hexahistidine tag resulted in a multiple products formation,therefore a peptide tag was modified by hydrazine functionality in order to perform labeling by hydra-zone formation chemistry.
