  • Patent number: 9278297
    Abstract: 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.

  • Patent number: 8092682
    Abstract: The present invention relates to a separation matrix comprised of a support to the surfaces of which polymer chains have been coupled, wherein each polymer chain presents recurring proton-donating groups and at least the surface of the support is substantially hydrophilic. In the most advantageous embodiment, the support is porous cross-linked agarose, the polymers are poly(acrylic acid) and the proton-donating groups are carboxyl groups. The matrix is useful e.g. to remove PEG from pegylated and/or native compounds in a liquid. Accordingly, the invention also encompasses a method, such as a chromatographic method, wherein the separation matrix according to the invention is used, for example as a pre-treatment of a reaction mixture that comprises unreacted PEG, pegylated proteins and native proteins.

  • Patent number: 8093373
    Abstract: The present invention relates to a method of isolating at least one plasmid from other components of a liquid, which method comprises the steps of providing a separation matrix comprised of one or more porous carriers, which carrier(s) present anion exchange groups on external surfaces as well as pore surfaces and a pore size distribution that does not allow access of plasmids to pore surfaces; contacting said matrix with the liquid to allow adsorption of the plasmids to ligands present on the separation matrix; contacting an eluent with the separation matrix to release the plasmids and recovering plasmids from a fraction of said eluent. Thus, the present method allows the plasmids to adsorb to the external surfaces of the matrix, while other components such as RNA is adsorbed onto the pore surfaces. In one embodiment, the matrix presents a DNA exclusion limit of at least about 270 base pairs; such as at least about 1,000 base pairs.
