Abstract: Methods for metabolic oligosaccharide engineering that incorporates derivatized alkyne-bearing sugar analogs as “tags” into cellular glycoconjugates are disclosed. Alkynyl derivatized Fuc and alkynyl derivatized ManNAc sugars are incorporated into cellular glycoconjugates. Chemical probes comprising an azide group and a visual or fluorogenic probe and used to label alkyne-derivatized sugar-tagged glycoconjugates are disclosed. Chemical probes bind covalently to the alkynyl group by Cu(I)-catalyzed [3+2] azide-alkyne cycloaddition and are 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, confocal microscopy, and mass spectrometry.

Abstract: The present disclosure relates to novel modular methods for generating a diversity of N-glycans of high mannose, hybrid and complex types. The present disclosure also relates to exemplary arrays of the synthesized N-glycans spotted onto aluminium oxide coated slides. These arrays can be used to detect and analyze binding interactions between the synthesized N-glycans and glycan binding molecules, such as HIV-1 neutralizing antibodies. The present disclosure also relates to methods for identifying agents that bind to various types of molecules on the arrays and to defining the structural elements of the molecules on the arrays that bind to those agents. The arrays and methods provided herein may be used for general epitope identification, drug discovery and as analytical tools. The present disclosure also provides useful glycans and epitope determinants that are useful in detecting, diagnosing, recurrence monitoring and preventing pathological diseases such as HIV.
