Saccharide microarrays with well-defined multivalency were prepared using glycodendrimers. The glycodendrimers with various generations and saccharides (α-Man, β-GlcNAc and β-Gal) were synthesized and immobilized on an acetylenyl-terminated gold substrate via click chemistry. The saccharide-immobilized substrates were analyzed using XPS, ellipsometry, cyclic voltammetry, contact angle goniometry, QCM and FTIR-RAS. The biological abilities of the saccharide-immobilized substrates were evaluated by SPR with the lectins of Con A, WGA and RCA120. Lectin binding to the glycodendrimer array was quantitatively analyzed, and association constants (KA) and kinetic rate constants (ka and kd) were evaluated. These kinetic constants were unique to each lectin, implying specificity of the multivalent effect of saccharide-lectin interaction.
