REGULATED GENETIC SUICIDE MECHANISM COMPOSITIONS AND METHODS |
摘要 |
<p>Embodiments of the present invention relates to the incorporation and use of a regulated genetic suicide mechanism for use in the improved purification of biologies, including adjunct use in various eubacterial minicell production and purification methodologies. Described herein are high- yield eubacterial minicell-producing strains with genetic modifications that comprise a regulated genetic suicide mechanism that irreparably destroys the parent cell chromosome such that live parental cells in a culture can be functionally eliminated at any time during the course of a minicell production and purification run. Embodiments of the present invention also describe methods useful in the elimination of live parental cells during the production of other cell-based biologies.</p> |
