WebAdd equal volume of chloroform to the recovered aqueous DNA layer. Repeat steps 2-4. Note: Phenol-chloroform is a hazardous waste - DO NOT pour down sink. Top Protocol: … Aqueous samples, lysed cells, or homogenised tissue are mixed with equal volumes of a phenol:chloroform mixture. This mixture is then centrifuged. Because the phenol:chloroform mixture is immiscible with water, the centrifuge will cause two distinct phases to form: an upper aqueous phase, and a lower organic phase. The aqueous phase rises to the top because it is less dense than the organic phase containing the phenol:chloroform. This difference in density is why phen…
