摘要: The present invention relates to a nonchromatographic-based process for the isolation of clinical grade plasmid DNA from bacterial cells. The exemplified methods described herein outline a scaleable, economically favorable protocol for the purification of clinical grade plasmid DNA from E. coli which includes CTAB-based precipitation of DNA in combination with adsorption of impurities to calcium silicate.
