Oligosaccharides play very crucial biological roles in the human body. They are structurally diverse and very challenging to analyze. In an attempt to contribute towards the analysis of oligosaccharides in the growing filed of 'Glycomics', we explored different ways to make novel efficient oligosaccharide tags to label N -linked oligosaccharides from glycoproteins. We synthesized and characterized various oligosaccharide tags which are useful to analyze the oligosaccharide by mass spectrometry, HPLC, and bioaffinity. In these tags we incorporated ar UV/fluorescent core, a biotin moiety and an amino/azido/alkyne terminus. We varied the structures of the tags for improved solubility in common organic solvents. These tags were used to label standard oligosaccharides, and the labeling efficiency was evaluated.
