title: Downstream processing of plasmid DNA for gene therapy and DNA vaccine applications.
abstract: Interest in producing large quantities of supercoiled plasmid DNA has recently increased as a result of the rapid evolution of gene therapy and DNA vaccines. Owing to the commercial interest in these approaches, the development of production and purification strategies for gene-therapy vectors has been performed in pharmaceutical companies within a confidential environment. Consequently, the information on large-scale plasmid purification is scarce and usually not available to the scientific community. This article reviews downstream operations for the large-scale purification of plasmid DNA, describing their principles and the strategy used to attain a final product that meets specifications.
