Cover Picture: Tools for Glycomics: Mapping Interactions of Carbohydrates in Biological Systems (ChemBioChem 10/2004)

5_10/2004The cover picture shows a tri(ethylene glycol) linker derivatized high-mannose nonasaccharide and a panel of related structural determinants which were used to prepare biophysical tools for the emerging field of glycomics. The background shows carbohydrate microarray data for high-mannose oligosaccharides bound by a panel of carbohydrate-binding proteins, including the HIV-inactivating proteins Cyanovirin-N and Scytovirin (see binding profiles in middle). DC-SIGN-mediated endocytosis of fluorescein-oligosaccharide conjugates (green) colocalized (yellow) with DC-SIGN (red) in human dendritic cells (top left) and transiently transfected HeLa cells expressing DC-SIGN (bottom right) were observed by confocal microscopy. Detailed information about the growing set of chemical and biophysical tools for use in glycomics and systems biology in general is reported in the concept article by P. Seeberger et al. on p. 1375 ff.
