Polysaccharides immobilized in polyacrylamide gel as high-capacity adsorbents for Bandeiraea simplicifolia lectin and...

A high-capacity adsorbent for lectins was easily prepared by immobilization of polysaccharides in a polyacrylamide gel. The properties of granulated guaran gel, used to purify by affinity chromatography the alpha-D-galactose-binding lectin from the seeds of Bandeiraea simplicifolia, were studied, as well as the binding of Concanavalin A (tetrameric) and succinylated Concanavalin A (dimeric) to a yeast mannan gel.
