We investigate the dimerization of SDF-1 in microM concentration and in the presence of sulfated oligosaccharides, using affinity capillary electrophoresis (ACE) hyphenated to electrospray ionization-mass spectrometry (ESI/MS). Chemokine stromal cell-derived factor-1 (SDF-1) is a potent chemoattractant involved in leukocyte trafficking and metastasis. Heparan sulfate on the cell surface binds SDF-1 and may modulate its function as a coreceptor of this chemokine. A major effect of the glycosaminoglycan binding may be on the quaternary structure of...

Analysis of sulfated oligosaccharrides by Mass Spectrometry

Florence Gonnet, Régis Daniel & Jeanine Tortajada
The structural heterogeneity of fucoidan with respect to linkage and sulfate position is still a limitation to trace clear correlations between the structure and biological activities of this polysaccharide, although much effort has been made during the past years to elucidate its structure complexes( DNA and polypeptides or polyamines). Recent studies have demonstrated the usefulness of tandem mass spectrometry for the sequencing of glycosaminoglycan oligosaccharides and the differentiation of sulfated isomers. Indeed, the fragmentation of...
