Latest Patents
Among his latest patents, one focuses on the purification of immunoglobulins. This invention relates to a separation matrix comprised of porous particles to which antibody-binding protein ligands have been immobilized. The ligand density is in the range of 5.0-10 mg/ml, and the gel phase distribution coefficient of the particles, expressed as K for a dextran of size 110 kDa, is above 0.65. The median particle diameter is between 65-84 μm, and the carbohydrate material is preferably highly cross-linked agarose. Another significant patent is a method of preparing a separation matrix. This method involves salt-treatment of a polysaccharide gel followed by cross-linking of the polysaccharide polymers. The process includes providing an aqueous solution of a gelatable native polysaccharide, lowering the temperature of the polysaccharide solution below its gelling point, and adding at least one salt to the resulting polysaccharide before cross-linking.
