    • The present disclosure relates to a method for metabolic oligosaccharide engineering that incorporates derivatized alkyne-bearing sugar analogs as “tags” into cellular glycoconjugates. The disclosed method incorporates alkynyl derivatized Fuc and alkynyl derivatized ManNAc sugars into a cellular glycoconjugate. A chemical probe comprising an azide group and a visual probe or a fluorogenic probe is used to label the alkyne-derivatized sugar-tagged glycoconjugate. In one aspect, the chemical probe binds covalently to the alkynyl group by Cu(I)-catalyzed [3+2] azide-alkyne cycloaddition and is visualized at the cell surface, intracellularly, or in a cellular extract. The labeled glycoconjugate is capable of detection by flow cytometry, SDS-PAGE, Western blot, ELISA or confocal microscopy, and mass spectrometry.
