摘要	Carbohydrate sequences are important for various biological processes. It has recently been estimated to have 100,000-500,000 carbohydrate structures in mammalian glycome. However, the peripheral carbohydrate determinants on N- and O-glycoproteins, glycolipids, polysaccharides and secreted free sugars are limited in numbers. Among these blood-group-related antigens the ABO(H)- and Lewis-types are particularly important. Negative-ion MS/MS has been successfully used in assignment of these epitopes on free reducing sugars but cannot be applied to reduced sugars, e.g. O-glycans typically released from mucins as alditols, or in positive-ion detection of either reducing or reduced oligosaccharides. In the present study, we investigate the fragmentation features of permethylated reducing and reduced sugars under positive-ion conditions of multi-stage MALDI-MS, and propose the concept of epitope ion and epitope spectrum for determination of peripheral blood-group related epitopes on secreted human milk oligosaccharides and N-glycans as reducing sugars and O-glycans as reduced alditols in conjunction with MALDI-MS glycan profiling.
