    摘要: The present invention relates to a method of producing novel chromatography media and use thereof for purification of biomolecules, such as proteins. The chromatography media comprises shell beads having an inner porous core and an outer shell. The method comprises providing buffering ligands in the core of the beads, and providing binding ligands aimed for biomolecule binding in the outer shell of the beads. This method makes it possible to optimize binding properties and buffering properties independently of each other which is especially to advantageous for production of chromatofocusing media.

    摘要: The present invention relates to a method for production of separation media using a so called Spinning Disc technology wherein the porosities of the beads are optimized in such a way that a desired biomolecule may be separated from a complex sample. The method comprises the following steps: a) feeding a 4-8% polysaccharide solution, which has a viscosity within 350-450 mPas, at 65-75° C. to one or more spinning discs at 3001-3010 rpm to form polysaccharide beads; b) capturing said formed polysaccharide beads in a capturing bath; wherein the porosity of the polysaccharide beads is controlled by varying the temperature of the capturing between 15 and 27° C., preferably between 17.5 and 24.6° C. The method yields porosities that prevent molecules larger than 150 000 g/mol to diffuse into the beads. The invention also relates to separation media produced by the method and use thereof for purification of biomolecules, in particular monoclonal antibodies.
