Abstract

The invention provides for a process to make high quality DNA in a cell-free system, free of bacteria contaminants, and optimally free of flanking bacterial gene coding sequences which can minimize or silence gene expression when used for expression inside a target cell. The cell-free system herein is a rapid method that produces a high fidelity, cleaner end product suitable for therapeutic applications with less effort and expense, and can be adapted to amplification of plasmid-like templates lacking unnecessary bacterial plasmid gene sequences. This increases efficiency of the system and increases the effectiveness of the end product expression vector. The end product can be easily used as a DNA therapeutic due to low incidence of bacterial cell components and bacterial toxins. The invention also provides a method for the production of DNA for any research or therapeutic purpose that is essentially free of inherent bacterial cell contaminants and/or bacterial toxins, as well as for the end product therapeutics including DNA vaccines.
