Abstract: The present invention relates to the purification of large scale quantities of active (infectious) adenovirus and AAV, especially for use in therapeutic applications. In particular, the invention provides improved methods for contacting such viruses with suitable chromatographic materials in a fashion such that any damage to the virus, particularly to surface components thereof, resulting from contact with such chromatographic materials is minimized or eliminated. The result is the ability to rapidly and efficiently purify commercial level quantities of active (infectious) virus suitable for use in therapeutic applications, e.g. gene transfer/therapy procedures.

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.
