Methods are presented for the production, affinity purification and analysis of plasmid DNA (pDNA). Batch fermentation is
used for the production of the pDNA, and expanded bed chromatography, via the use of a dual affinity glutathione S-transferase
(GST) fusion protein, is used for the capture and purification of the pDNA. The protein is composed of GST, which displays
affinity for glutathione immobilized to a solid-phase adsorbent, fused to a zinc finger transcription factor, which displays
affinity for a target 9-base pair sequence contained within the target pDNA. A Picogreen™ fluorescence assay and/or anx ethidium
bromide agarose gel electrophoresis assay can be used to analyze the eluted pDNA.
