General Description

  • This solution contains a mixture of pure chloroform, isoamyl alcohol and phenol saturated with Tris-EDTA, with a stabilized pH of 8.0


  • Phenol-Chloroform-Isoamyl alcohol mixture solution (25:24:1) is used in the extraction of nucleic acids, DNA, and RNA
  • When nucleic acids are extracted with the Phenol-Chloroform-Isoamyl alcohol mixture solution, a clear component separation is achieved. The proteins present in the sample are denatured and removed (collected in the organic phase or in the interphase), while nucleic acids remain in the aqueous phase. The chloroform denatures proteins and facilitates the separation of the aqueous and organic phases, and the isoamyl alcohol reduces foaming during extraction.
  • It is also used to generate DNA minisatellite fingerprints
