Purification of plasmid DNA from clarified and non-clarified Escherichia coli l...

In this study, berenil was tested as a ligand, specifically to purify plasmids of different sizes pVAX1-LacZ (6.05 Kbp) and pCAMBIA-1303 (12.361 Kbp) from clarified Escherichia coli alkaline lysates. For this purpose, chromatographic experiments were performed using Sepharose derivatized with berenil. The results showed that both pDNA molecules are completely purified using lower amounts of salt in the eluent t...
