  • Lysis and neutralization method for production of pharmaceutical grade plasmid DNA
    Publication number: 20050079534
    Abstract: The present invention is a short duration lysis and neutralization process developed for the production of pharmaceutical grade plasmid DNA. This process includes the mixing of concentrated bacterial suspension and lysis solution through a “T” or “Y” shaped device, followed by the addition of neutralization solution through a another “T” or “Y” shaped device. A thorough mixing of bacterial suspension, lysis solution, and neutralization solution was achieved by addition of static mixer(s) at post-lysis and post-neutralization steps. The neutralized bacterial suspension was clarified by bag-filtration to remove macromolecules and host cell chromosomal DNA-protein precipitates.
