Unlabeled Glycan Workflow

Glycans are often derivatized prior to analysis, but it is also possible to analyze both N-glycans and O-Glycans in a label-free form, typically using ion chromatography (IC) or liquid chromatography with charged aerosol detection. IC technique is sensitive and selective and resolves glycans according to charge, size, composition, isomers and linkage. As an alternative, liquid chromatography with the correct choice of detector can also be used.

High performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD) on systems such as the Dionex ICS-6000 Hybrid HPIC System, is a well-established analysis method to characterize released Glycans. The separation is exceptionally selective for sugars and resolves glycans based on charge, size, composition, isomers and linkages. It is even possible to separate glycans based on sialic acid linkage, providing valuable information not only about the sugar sequence of a glycan, but also the subtle linkage differences that may indicate disease states.
