Abstract

Chondroitin sulfate tetrasaccharide ligand conjugates, namely GlcA-GalNAc6S-GlcA-GalNAc4S6S (CS-C+E) 1, GlcA2S-GalNAc6S-GlcA2S-GalNAc4S6S (CS-D+T) 2, GlcA-GalNAc4S6S-GlcA-GalNAc4S (CS-E+A) 3, GlcA-GalNAc4S6S-GlcA-GalNAc6S (CS-E+C) 4, and GlcA-GalNAc4S6S-GlcA-GalNAc4S6S (CS-E+E) 5, were systematically synthesized using a disaccharide building block 6. Synthesized CS tetrasaccharide structures were immobilized onto gold-coated chips to prepare array-type sugar chips, and the binding properties of protein were evaluated by surface plasmon resonance imaging biosensor. CS-D+T, CS-E+A, CS-E+C, and CS-E+E showed greater affinity for basic fibroblast growth factor than did other tetrasaccharides (CS-C+D, C+E, D+D).
