A matrix comprising a water-insoluble beta -1,3-glucan gel in the shape of beads with diameters within the range of about 5 to 1000 mu is prepared by, for example, dispersing an alkaline aqueous solution of a water-soluble beta -1,3-glucan in a water-immiscible organic solvent, and adding an organic acid to the resultant dispersion. The matrix is useful as carrier materials for immobilized enzymes, affinity chromatography, gel filtration, ion exchange and other applications.
