Web2. Add 0.5ml of phenol:chloroform:isoamylalcohol (25:24:1). That phenol was saturated with TE (10mM Tris, 7.5, 1mM EDTA) previously for mixing on chloroform and isoamylalcohol. 3. Mix by vortexing at the maximum speed fork 1 minute. Other, vortex for 10 seconds and then transfer to eppendorf stirrer or an over-the-top rotator on 5 recorded. 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…
