摘要： Provided is a manufacturing method for monolithic structure that is a porous body formed of polysaccharide being a naturally-occurring polymer, has continuous pores with an average pore diameter suitable for biomolecule separation, and allows formation into arbitrary shape. The polysaccharide monolithic structure is manufactured by a method including a first step of obtaining a polysaccharide solution by dissolving polysaccharide into a mixed solvent of a first component and a second component at temperature lower than a boiling point of the mixed solvent, and a second step of obtaining polysaccharide monolithic structure by cooling the polysaccharide solution, wherein the first component is a solvent selected from lactate, and the second component is a solvent selected from water, lower alcohol, and a combination thereof. The monolithic structure obtained is a porous body having continuous pores with an average pore diameter of 0.01 to 20.0 micrometers, and a thickness of 100 micrometers or more.

摘要： A problem is to provide a monolithic structure that is a porous body formed of a polysaccharide being a naturally-occurring polymer, and has continuous pores having an average pore diameter suitable for biomolecule separation to allow formation into an arbitrary shape, and a manufacturing method therefor. A solution is to manufacture the polysaccharide monolithic structure by a method including a first step for dissolving a polysaccharide into a mixed solvent including a solvent into which the polysaccharide is soluble and a solvent into which the polysaccharide is insoluble, at a temperature lower than a boiling point of the mixed solvent, to give a polysaccharide solution, and a second step for cooling the polysaccharide solution to give the polysaccharide monolithic structure. The polysaccharide monolithic structure obtained is a porous body having continuous pores having an average pore diameter of 0.01 to 20 micrometers and a thickness of 100 micrometers or more.
