title: Rabbit and rat hepatic lectins have two sugar-combining sites per monomeric unit.
abstract: Binding characteristics of the galactose/N-acetylgalactosamine-specific, hepatic lectins of rabbit and rat were studied using small, high-affinity ligands containing two and three N-acetylgalactosamine residues per molecule [Lee, R. T. and Lee, Y. C. (1987) Glycoconjugate J. 4, 317-328]. These N-acetylgalactosamine cluster ligands have the receptor-ligand dissociation constants in nanomolar range, so that the lectin-ligand interaction can easily studied by an equilibrium (gel chromatography) or non-equilibrium (fast filtration assay) method. The results suggest that there exist on the average two N-acetylgalactosamine-combining sites per monomeric unit of both the rabbit and rat lectins.
