    摘要: The present invention relates to method of manufacturing a sulphonate-functionalized (S-functionalized) cation exchanger, which method comprises reacting olefinic groups with bisulphite in the presence of at least one amine oxide, such as N-methyl morpholine oxide (NMO). The olefinic groups of the carrier may be allyl groups; which may be provided on extenders such as polyhydroxyfunctional polymers. In one embodiment, the carrier is made of agarose with improved flow pressure properties.

    摘要: 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.

    摘要: The present invention relates to a method for post-modification of a macroporous polymeric support comprising one or more unreacted double bonds, which method includes the steps of contacting the support with a liquid comprising a grafting compound; and initiating a free radical reaction in the mixture obtained, wherein the grafting compound is comprised of a double bond as a reactive group coupled to a linear or cyclic chain of carbon. The grafting compound can be illustrated with vinyl ethers and/or styrene and styrene derivatives.
