Synthetic assembly of a series of glycopolymers having sialyl α2-3 lactose moieties connected with longer spacer arms.

Glycopolymers having sialyl α2-3 lactose moieties via longer spacer arms were systematically prepared from the corresponding glycomonomers. Radical polymerization of glycomonomers gave a series of glycopolymers displaying various sugar densities. Fluorometric analyses of wheat germ agglutinin (WGA) against the glycopolymers were conducted and the results showed unique binding specificities on the basis of sugar densities.
