Filed: 1993-06-29
Abstract: PURPOSE:To prevent the electroendosmosis without being accompanied by a reduction in get strength and other physical property changes by cationizing a neutral polysaccharide, and mixing the resulting derivative to agarose in a specified ratio. CONSTITUTION:An equipotential electrophoretic agarose is formed by mixing a derivative (cationized polymer) obtained by cationizing a neutral polysaccharide to agarose in an amount of 0.01-20 parts by weight.
