Abstract
The present invention relates to a separation matrix comprised of a porous support to which ligands have been immobilized, 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.
