Glycan Purification

Glycan purification is an essential technology for glycoprofiling. Salts, detergents, proteins, and other contaminants can interfere with fluorescent labeling of released glycans. Exo- and endoglycosidases can contaminate HPLC columns and interfere with mass spectrometry methods for the analysis of glycans.

A number of technologies have been developed for the purification of glycans from proteins, salts, and detergents by our partners at Ludger Ltd:

LudgerClean EB10 cartridges have been designed for purification of glycans from proteins, salts, and detergents. The cartridges contain a unique graphitised carbon material which acts like a super-hydrophobic resin that binds even very hydrophilic glycans.

The LudgerClean PBM Post-Glycosidase Clean-Up plate has been developed for removal of glycosidases prior to MS analysis in a 96-well format.

LudgerClean CEX cartridges purify O-glycans from non-carbohydrate material including salts, proteins, and detergents. The cartridge contains a cation exchange resin.

LudgerClean Pre-permethylation Plates are used for the removal of excess salts, detergent, proteins and other impurities after the release of N-glycans from glycoproteins. This clean-up plate is used to enrich N-glycans prior to performing permethylation of released glycans.

EB10 Cartridges

Ludger EB10 cartidges have been designed for purification of glycans from proteins, salts, and detergents.

Applications include cleanup of glycans following hydrazinolysis, endoglycosidase digests (including PNGase F digests), enzyme treatment, and before and after fluorescent labeling.

PBM Glycosidase Removal Plate Image

PBM Glycosidase Removal

The LudgerClean PBM Glycosidase removal plate was developed for the capture of endo- and exoglycosidases after deglycosylation to prevent contamination of HPLC columns during subsequent chromatographic analysis. The plate can also be used to remove glycosidases or other proteins before mass spectrometry analysis of glycans.
