Phenol/Chloroform â This is a mixture of buffer-saturated phenol and chloroform, usually close to 1:1 for DNA purification with other ratios sometimes used for RNA purification. Isoamyl alcohol is sometimes included as an anti-foaming agent, but is generally thought to be an inert and optional addition.hloroform â This is normally used after phenol or phenol/chloroform extractions. While pure chloroform doesnât work as well as the organic solutions mentioned above for protein extraction, it works well for extracting phenol from aqueous solutions.
