CHARACTERIZATION OF N-GLYCANS USING EXOGLYCOSIDASES

摘要

The present disclosure provides methods for analyzing structure and/or composition of N-glycans. Such methods often involve digestion of N-glycans with multiple exoglycosidases. In some embodiments, N-glycans are digested with multiple exoglycosidases simultaneously. In some embodiments, N-glycans are digested with multiple exoglycosidases sequentially. In some embodiments, methods in accordance with the present disclosure involve comparison of cleavage products of N-glycans that have been digested with multiple exoglycosidases simultaneously to N-glycans that have been digested with multiple exoglycosidases sequentially.
