Glycoprotein Quantification

Glycoprotein Quantification

Protein glycosylation is one of the major post-translational modifications that can significantly impact protein folding, distribution, stability, conformation, and activity. Glycoprotein abundance, glycosylation degree, and glycan structure changes are closely related to many diseases (such as genetic diseases, immunodeficiency, cardiovascular diseases, and cancer). The research on glycoproteomics has become popular, increasing the demand for the development of quantitative glycomics strategies. These strategies need to be able to sensitively monitor the abundance and structural changes of glycans. The role and characteristics of glycans in biological systems can be clarified using these strategies.

In the past, people focused their research on the enrichment and separation of glycoproteins/glycopeptides, identification of glycosylation sites, and glycan structure analysis. So far, the development of quantitative glycomics has lagged slightly behind other studies. At present, a combination of multiple analytical techniques (such as capillary electrophoresis, liquid chromatography, and mass spectrometry) is mainly used to analyze glycoprotein quantitatively. To enhance the sensitivity in spectroscopy and mass spectrometry, it is necessary to label with ionic and/or hydrophobic reagents during the analysis. Labeling with stable isotope reagents has also been considered a feasible strategy to achieve relative quantification.
