    • A method for making functionalized porous crosslinked polysaccharide gel coated structures used as liquid chromatography media is provided. The method includes impregnating a porous substrate with a room temperature stable aqueous polysaccharide solution containing water, 0.1% to 20% of a polysaccharide, 18% to 54% of a gel-inhibiting agent to prevent the gel from re-gelling, and 0.001% to 10% of an anionic fluorosurfactant for optimum solution coatability onto the substrate, each concentration is by total weight of the aqueous solution. Next water is evaporated from the coating, followed by exposing the dehydrated coating to a gelling agent thereby forming a porous polysaccharide gel coated substrate. Next the gel coated substrate is exposed to a crosslinking agent forming a porous crosslinked polysaccharide gel coated substrate. Next, the gel coated substrate is functionalized by contacting the porous polysaccharide gel coated substrate with sodium 3-bromopropanesulfonate, thereby attaching sulfopropyl ligands to the gel coated substrate, resulting in a functionalized porous absorptive polysaccharide gel coated chromatography structure. When the functionalized gel coated chromatography structure is used as liquid chromatography media, and a protein (e.g. lysozyme) containing solution contacts the media, the sulfopropyl ligands attached to the gel coated chromatography structure will bond to the protein, thereby removing the protein from the protein containg solution.
    • 提供了用作液相色谱介质的功能化多孔交联多糖凝胶涂层结构的方法。 该方法包括用含有水,0.1%至20%的多糖,18%至54%的凝胶抑制剂的室温稳定的水性多糖溶液浸渍多孔基材以防止凝胶重新凝胶化,并且0.001% 至10%的阴离子含氟表面活性剂,用于在基材上获得最佳的溶液涂布性,每种浓度均为水溶液的总重量。 接下来的水从涂层中蒸发,然后将脱水涂层暴露于胶凝剂,从而形成多孔多糖凝胶涂覆的基质。 接下来,将凝胶涂覆的基底暴露于形成多孔交联多糖凝胶涂覆的基底的交联剂。 接下来,通过使多孔多糖凝胶涂覆的基质与3-溴丙磺酸钠接触使凝胶涂覆的底物功能化,从而将磺丙基配体连接到凝胶涂覆的基质上,得到官能化的多孔吸收多糖凝胶涂层色谱结构。 当将功能化凝胶涂层色谱结构用作液相色谱介质,并且含有蛋白质(例如溶菌酶)的溶液与培养基接触时,附着在凝胶涂层色谱结构上的磺丙基配体将与蛋白质结合,从而从蛋白质中除去蛋白质 包含解决方案

    • Room temperature stable, non-gelling polysaccharide solutions such as agaroses, dextrans and cyclodextrans are made by the present invention. It has been found that by incorporating certain gel-inhibiting additives into an aqueous polysaccharide solution, the gel point is reduced or eliminated and the solution remains liquid at room temperature indefinitely. Additives that have been found to work include salts, such as lithium chloride and zinc chloride and bases, such as sodium hydroxide and lithium hydroxide. Mixtures of said salts and said bases can also be used with the same desired results. The composition of these solutions of the present idea can be further modified to include other additives, such as organic co-solvents or non-solvents, pH modifiers, surfactants or other polymers to customize the properties of the solution to improve the processability for the desired application and to form structures such as films, beads and coated porous substrates.
