  • Low molecular weight displacers for protein purification in hydrophobic interaction and reversed phase chromatographic systems
    Patent number: 6239262
    Abstract: A method for purification of proteins by displacement chromatography in hydrophobic interaction and reversed phase chromatographic systems uses low molecular weight (less than about 10,000) surface-active compounds as displacers. Examples of effective displacers are benzethonium chloride, benzyltributylammonium chloride, and tetrahexylammonium chloride.
