Studies on lectins. XL. O-glycosyl derivatives of Spheron in affinity chromatography of lectins.
Free monosaccharides can be used for direct glycosylation of Spheron, a spherical macroporous hydroxyalkyl methacrylate-ethylene dimethacrylate copolymer, in a reaction that proceeds at room temperature in dioxane medium under catalysis of dry HCl or BF3. Derivatives of L-fucose, D-galactose, D-glucose, D-mannose, N-acetyl-D-galactosamine and N-acetyl-D-glucosamine thus prepared from Spheron beads have been shown to be efficient affinity carriers in isolation of lectins from seeds of Canavalia ensiformis D.C. (concanavalin A), Dolichos biflorus L., Glycine soja (L.) Sieb. et Zucc., Lens esculenta Moench, Ricinus communis L., Ulex europaeus L. and from albumin glands of the garden snail Helix pomatia L.
