    摘要: The present invention relates to a separation matrix comprised of ligands coupled to the surfaces of a porous support, such as one or more porous particles, wherein the ligands provide at least one chemical gradient within the support. In the most advantageous embodiment, the chemical gradient is a ligand density gradient. The invention also relates to a method of providing a separation matrix comprising ligands coupled to the surfaces of a porous support, in which method at least one ligand density gradient is provided by solvent-controlled diffusion of at least one reagent into the porous support.

    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 running ion exchange chromatography on a media comprising shell beads having an inner porous core and an outer shell, wherein the inner core is provided with ligands whose charge changes with pH and the shell is provided with charged ion exchange ligands, the method comprising the following steps: a) adsorbing sample molecules on the shell ligands at a first pH; b) causing a discharge of the inner core ligands at a second pH by addition of a buffer substance that is able to increase its charge having the same sign/type as that of the core ligands, which at the same time causes release of ions from the inner core ligands and thereby an increase in ionic strength that displaces the sample molecules from the shell ligands i.e. causes an elution.
