Combining cryognic ion spectroscopy with ion mobility for the study of glycan fragmentation

Robert Paul Pellegrinelli

The importance of glycans in biological processes are matched by their structural complexity. Coating the surface of most living cells, glycans play key roles in many biological processes, and the role they play is closely related to their structures. Stru ...
