Patent number: 7687619Abstract: 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.Type: GrantFiled: February 3, 2005Date of Patent: March 30, 2010Assignee: Millipore CorporationInventors: Wilson Moya, Neil P.
