QIAGEN Plasmid Kit procedures.

Neutralized bacterial lysates are cleared by centrifugation. The cleared lysate is then loaded onto the anion-exchange tip where plasmid DNA selectively binds under appropriate low-salt and pH conditions. RNA, proteins, metabolites, and other low-molecular-weight impurities are removed by a medium-salt wash, and ultrapure plasmid DNA is eluted in high-salt buffer. The DNA is concentrated and desalted by isopropanol precipitation and collected by centrifugation.
