As a result, first-generation high-performanceliquid chromatography (HPLC) methods based on anion-exchange and sizeexclusion have been developed but are difficult to accommodate production atlarge scale and still result in compromised purity (1,2). The success of DNAvaccines in animal models and the initiation of human trials (3,4) has led to aneed to increase the level of supercoiled plasmid purity as well as the methodologyutilized to produce these plasmids at large scale. Several parameters ofthe purification process need to be addressed:
