Abstract
The present invention relates to a method of manufacturing a chromatography matrix comprising providing a polysaccharide carrier comprising available hydroxyl groups; and reacting said hydroxyl groups with vinyl sulphonate to provide a sulphonate-functionalized (S-functionalized) cation exchanger. The hydroxyl groups of the carrier may be hydroxyls of the agarose polymer; or alternatively they may be provided on extenders such as polyhydroxyfunctional polymers. In one embodiment, the carrier is made of agarose with improved flow pressure properties.
