SPRi Imaging of Oligosaccharides/Proteins Interactions

SPRi Imaging of Oligosaccharides/Proteins Interactions

8 Dec 2015

The majority of proteins are glycosylated: they possess oligosaccharide chains and are hence termed glycoproteins. Oligosaccharides, also called carbohydrate or sugar, are often quite large (as large as some protein domains for example) and they have many functions in molecular interactions. This application note highlights the development of an oligosaccharide chip (surface functionalization, density of immobilization, spacer arm length) on the same SPRi platform using conductive polymers. These results are highlighted through the example of interactions between HS and SDF-1 α chemokine.
