DNA Purification

A large amount of extracted plasmid DNA generally needs further purification, commonly used column chromatography and cesium chloride gradient centrifugation. All commonly used purification methods take advantage of the relatively small size of plasmid DNA and the covalently closed circular shape. For example, the separation of plasmid and chromosomal DNA by cesium chloride-ethidium bromide gradient equilibrium centrifugation depends on the amount of ethidium bromide binding to the linear and closed-loop DNA molecules.
