Phenol: The phenol used for biochemistry comes as a water-saturated solution with Tris buffer, as a Tris-buffered 50% phenol, 50% chloroform solution, or as a Tris-buffered 50% phenol, 48% chloroform, 2% isoamyl alcohol solution (sometimes called "25:24:1"). Phenol is naturally somewhat water-soluble, and gives a fuzzy interface, which is ...
