Identification of N-glycans from CaG, IQG, and HEG using MALDI-FOF MS and MS/MS spectrometry. N-glycan of CaG mass (MS) spectrum had main peaks with m/z 1175.5, Hex₇; m/z 1337.5, Hex₈; m/z 1499.6, Hex₉ and m/z 1282.5, Hex₃HexNAC₃dHex₁. N-glycan of IQG had main peaks in MS spectrum with m/z 1282.5, Hex₃HexNAC₃dHex₁; m/z 1485.6, Hex₃HexNAC₄dHex₁ and 1752.2, Hex₇HexNAC₆. N-glycan of HEG had main peaks in MS spectrum with m/z 1175.2 Hex7 and m/z 1752.2, Hex₇HexNAC₆. Proposed structure was analyzed by N-glycan sequence data library matched with MS/MS spectrum
