WebThe phenol-chloroform mixture is immiscible with water, therefore when centrifuged, the samples form two distinct phases. The lower (organic) phase and phase interface contain denatured proteins, while the less-dense upper (aqueous) phase contains nucleic acids. Importantly, the phase extraction of DNA and RNA is pH-dependent, when the pH is ... WebAfter solubilization, the addition of chloroform causes phase separation (much like extraction with phenol:chloroform:isoamyl alcohol), where protein is extracted to the organic phase, DNA resolves at the interface, and RNA remains in the aqueous phase.
