  • Patent number: 7326555
    Abstract: A process for purifying virus particles, especially recombinant adenovirus vector particles, is presented. The process relies on various combinations of cell lysis, detergent-based precipitation of host cell contaminants away from the virus, depth filtration or centrifugation, ultrafiltration, nuclease digestion and chromatography to robustly and economically produce highly purified product. This process results in contaminating DNA levels which are consistently below detectable levels.
