In this method, a mixture of TE (or [[Tris]]-[[Ethylenediaminetetraacetic acid]]) and [[phenol]] is combined with an equal volume of an aqueous [[DNA]] sample. After agitation and centrifugal separation, the aqueous layer is extracted, and further processed with [[diethyl ether|ether]]. Then the DNA is concentrated by [[ethanol precipitation]]. ==See also== *[[Phenol-chloroform extraction]] ==References== *http://mycoplasmas.vm.iastate.edu/lab_site/methods/DNA/phenol.html [[Category:Molecular biology]] {{chem-stub}}
