Application

3′-N-Acetylneuraminyl-N-acetyllactosamine is a glycan component of O-gylcopeptides. 3′-Sialyl-N-acetyllactosamine can be used to make an avian receptor analogue glycoprobe to study the binding of influenza viruses such as the North American lineage subtype H7N2 virus A/New York/107/2003 (NY107). 3′-Sialyl-N-acetyllactosamine is used as a reference material in the analysis of milk oligosaccharides.

Review of O-Linked Glycoproteins

O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
