  • Methods for purifying cystic fibrosis transmembrane conductance regulation
    Patent number: 5939536
    Abstract: The present invention provides a method for purifying a membrane associated protein, e.g., cystic fibrosis transmembrane conductance regulator (hereinafter CFTR) in a functional form. The method involves contacting a membrane-associated protein-membrane fraction complex with a detergent forming a solubilized complex and chromatographically isolating the membrane-associated protein from the solubilized complex in a functional form. The functional form of the purified membrane-associated protein of the present invention preferably is sufficiently pure to allow its introduction into humans for therapeutic purposes.
