Ion Analysis

High resolution glycan analysis has become an important part of biopharmaceutical API production and quality control. Liquid chromatography (LC) is now a well-established technique in this field but the resolution of similar isomeric glycan structures is still a challenge. Here we show that the addition of ion mobility spectroscopy (IMS) in a hyphenated LC-IMS-MS setting allows for the high resolution of N-glycan isomers during positive ion analysis. We have identified unique features in the IM chromatograms to help differentiate a range of isomeric N-glycans for both RFMS labelled glycans and glycopeptides.<br>

Glycan Sequencing

Determining glycan structures is vital to comprehend cell-matrix, cell-cell, and even intracellular biological events. Glycan sequencing, which determines the primary structure of a glycan using tandem mass spectrometry (MS/MS), remains one of the most important tasks in proteomics. Analogous to peptide de novo sequencing, glycan de novo sequencing determines the structure without the aid of a known glycan database. We show in this paper that glycan de novo sequencing is NP-hard. We then provide a heuristic algorithm and develop a software program to solve the problem in practical cases. Experiments on real MS/MS data of glycopeptides demonstrate that our heuristic algorithm gives satisfactory results on practical data.
