• Detection of Glycosylation Sites (N-glycan, O-glycan) in Recombinant Protein Vaccines

Recombinant protein vaccines are a novel type of vaccine product produced using genetic engineering technology in organisms or cell systems. During the production process of these vaccines, glycosylation reactions may occur, where sugar chains are added to the N-site (e.g. asparagine) and O-site (e.g. serine or threonine) of the protein. Glycosylation is an important post-translational modification of proteins that affects their stability, solubility, biological activity, etc.
