Processing of plasmid DNA with ColE1-like replication origin.
With the increasing utilization of plasmid DNA as a biopharmaceutical drug, there is a rapidly growing need for high quality plasmid DNA for drug applications. Although there are several different kinds of replication origins, ColE1-like replication origin is the most extensively used origin in biotechnology. This review addresses problems in upstream and downstream processing of plasmid DNA with ColE1-like origin as drug applications. In upstream processing of plasmid DNA, regulation of replication of ColE1-like origin was discussed. In downstream processing of plasmid DNA, we analyzed simple, robust, and scalable methods, which can be used in the efficient production of pharmaceutical-grade plasmid DNA.
