Latest Patents
One of her latest patents is titled "Process for the purification of antibodies." This invention relates to a method for purifying antibodies from impurities in a liquid. The process involves contacting the liquid with a first chromatography resin that has multi-modal ligands immobilized on a support. This allows for the adsorption of antibodies to the resin. The method further includes adding an eluent to release the antibodies from the resin and contacting the resulting eluate with a second chromatography resin.
Another significant patent is "Use of urea variants as affinity ligands." This invention focuses on an IgG-binding compound that has a specific affinity for human IgGs of κ-type. The compound features an N,N-alkylated urea moiety situated between an aromatic part and a linear or cyclic aliphatic group. This compound binds to a pocket-shaped binding site present on all human IgG κ-Fabs, making it a valuable ligand for human IgGs of κ-type.
