Glycosylation Service

Glycosylation is the process of adding sugars to proteins or lipids under the control of enzymes, which occurs in the endoplasmic reticulum and Golgi apparatus. Under the action of glycosyltransferase, the sugar is transferred to the protein, and the amino acid residues on the protein are covalently bonded. Proteins undergo glycosylation to form glycoproteins. Glycosylation is an important modification of protein, and it can regulate protein function. Glycosylation can significantly influence protein stability, biological activity, and pharmacokinetics of the final products.


Lectin affinity method is currently a widely used method of separation and enrichment in glycoproteomics. Lectin is a type of sugar-binding protein that can specifically recognize and bind to a specific glycosyl sequence in a monosaccharide or glycan with a special structure. They are reversibly non-covalently bound to sugar chains, glycoproteins or After the glycopeptide is captured by the lectin, a specific monosaccharide is usually used to elute the glycoprotein or glycopeptide by competing with the lectin. After the protein is digested by enzymes, lectin is used to enrich N-glycosylated peptides, and then the sugar chains connected to asparagine residues (Asn) are excised in H218O with N-glycamidase (PNGase). This treatment caused an increase in the molecular weight of Asn by 2.9890 Da. Finally, a high-precision LC-MS mass spectrometer was used to detect the peptide after deglycation to confirm the change of the molecular weight and the theoretical molecular weight of the desaccharide and the sequence of the glycosylation modified peptide to determine the N-glycosylation site of the protein.
