Phenol-chloroform method
Did you know?
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… WebPopular answers (1) first of all since phenol is immiscible in water it forms the basis for phase separation, being heavier it settles down, but when water and phenol are mixed by …
