CD BioGlyco is committed to providing a one-stop customized service in the field of glycoprotein-based vaccine development, and our advanced technology allows us to design and synthesize chemically defined glycoconjugates vaccines with higher safety and efficacy.
By conjugating low-immunogenicity carbohydrate antigen to a protein carrier through a linker for optimal antibody responses, this approach allows for the generation of antibodies against both protein carrier and less immunogenic glycan structures, thus enabling vaccine to target carbohydrate antigens. Glycoconjugates currently play a central role in vaccination, but there are few examples of synthetically defined glyco-vaccine candidates.
Generally, even in cases where glycoproteins are synthesized in pure form, non-specific approaches are used to bind the glycoproteins to protein carriers. This leads to mixtures of glycoforms with different glycan-to-protein ratios and glycosylation sites, and potentially different immunological and pharmacokinetic properties. The recently developed frontier technologies in oligosaccharide synthesis and protein site-specific functionalization help a lot in designing and constructing chemically defined glycoproteins, to dissect the vaccine structure on immune response and produce candidate vaccines with higher safety and effectiveness.
