Cscl plasmid purification

WebPlasmid purification is a technique used to isolate and purify plasmid DNA from genomic DNA, proteins, ribosomes, and the bacterial cell wall. A plasmid is a small, circular, double-stranded DNA that is used as a carrier of specific DNA molecules. WebSeveral parameters of the purification process need to be addressed: • The ability to prepare supercoiled plasmid at purity levels acceptable for clinical material. • The ability to prepare clinical grade supercoiled plasmid that will be scalable in order to produce gram quantities of product.
