    摘要: The present invention relates to a separation matrix comprised of a porous support to which ligands have been immobilised, wherein said ligands comprise at least one sulphonamide and the R group of the sulphonyl comprises an aromatic group. The nitrogen of the sulphonamide may be a secondary or tertiary amine. The invention also relates to a chromatography column that contains the described separation matrix, as well as to a method of isolating immunoglobulin-like compounds by adsorption to the separation matrix.

    摘要: The invention relates to a method for removing a positively charged substance from an aqueous liquid (I) by contacting the liquid with a cation-exchanger (1), possibly followed by a subsequent desorption of said substance. The cation-exchanger is selected to be capable of (a) binding to said substance by cation-exchange in an aqueous liquid reference (II) at an ionic strength corresponding to 0.3 M NaCl and (b) permitting a break through capacity for said substance 3200%, such as 3300% or 3500%, of the break-through capacity of said substance for a reference cation-exchanger (2) containing sulphopropyl groups —CH2CH2CH2SO2O—. The cation exchange ligands have an at least bimodal function by comprising a cation exchanging group and a separate hydrogen-bonding atom. The invention also relates to a method for testing the appropriateness of a cation-exchanger for removing a substance from a liquid and novel cation exchangers.

    摘要: The present invention relates to a method for depletion of undesired molecules and/or enrichment of desired molecules from a sample comprising high abundant as well as low abundant molecules, comprising the following steps: a) providing a separation material comprising a solid phase (beads) comprising an inner porous core material comprising magnetic particles and an outer porous shell with a porosity equal or denser than that of the shell; b) adding the sample to the separation material; c) adsorbing a first fraction of molecules with a molecular weight of 500-50 000 Da in the core and simultaneously excluding a second fraction of molecules from binding to the core and the shell, wherein the molecular weight of the second fraction molecules is at least 5 preferably 10 times higher than the molecular weight of the first fraction and d) eluting the desired molecules from the separation material, wherein step d) and optionally step c) is performed using an oscillating power/field applied over the separation material.The first fraction of molecules are for example drugs with a mw of about 700 Da, small proteins/peptides with an mw of about 7000 Da or proteins with a mw of about 40 000 Da.
