Abstract
A chromatographic material comprising an inorganic support-polysaccharide particle matrix is described. The matrix comprises an inorganic support having a high surface density of hydroxyl groups and, covalently attached thereto, insoluble particles of a polysaccharide. The free hydroxyl groups of the matrix can be activated, say, by treatment with cyanogen bromide or sodium metaperiodate, to form active sites where ligands can be attached for affinity chromatography.
