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 separation matrix comprised of a porous support to which ligands have been immobilised, wherein said ligands comprise at least one aliphatic sulphonamide. 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 a separation matrix that comprises aliphatic sulphonamide ligands.

摘要: Disclosed is a method for activating a solid support material with epoxy groups and for immobilising ligands thereon, utilising phase transfer catalytic conditions. The method permits the introduction of epoxy groups and specific nucleophilic ligands on the support material with a high level of substitution. Furthermore, the invention provides a general method for immobilising a ligand for use in a wide variety of chromatographic separation procedures such as ion exchange chromatography, hydrophobic interaction chromatography (HIC), reverse phase chromatography (RPC), or affinity chromatography.
