2-AB labelled triantennary oligosaccharide Triantennary N-glycan that contains terminal sialic acid residues, (size: 100pmol) m/z: 2999.0794A3 2-AB Glycan is a mixture of tri-sialylated, tri-antennary N-linked oligosaccharides found on bovine serum fetuin. The two principal components are structural isomers both fully sialylated on the non-reducing terminal galactosyl residues but differing in the distribution of a2,3 and a2,6 linked sialyl residues and the linkage one of the galactoses.
