Glycoprotein & glycopeptide

Glycoprotein & Glycopeptide


Glycoproteins are used as process controls for glycan release, and consecutive release followed by labelling. Glycoprotein standards that are widely available are IgG, mAbs and fetuin. These are useful during endoglycosidase release (N-glycans), hydrazinolysis, Orelea or beta elimination (generally O-glycans) and acid release (during monosaccharide/sialic acid analysis). Fetuin, IgG and mAbs can also be used as process controls for proteolytic digestion during glycopeptide mapping.

Glycopeptides are used as process controls for glycan release, and consecutive release followed by labelling. They are useful during both endoglycosidase release (N-glycans) and acid release (during monosaccharide/sialic acid analysis). They can also be used as purified standards during glycopeptide mapping.

The Fetuin Glycoprotein Standard is a highly sialylated glycoprotein standard which can be used as a positive control during glycan release and labelling (particularly for DMB sialic acid analysis). Fetuin exists in a variety of glycoforms containing bi-, tri-, and tetraantennary N-linked oligosaccharides with variable sialylation, as well as O-linked glycans.
