ROTI®Phenol/Chloroform/Isoamyl alcohol is re-distilled phenol, equilibrated in TE buffer, premixed with high purity chloroform and isoamyl alcohol.
ROTI®Phenol/Chloroform/Isoamyl alcohol has proven itself in many research laboratories for the isolation of nucleic acids and is an ideal complement to pure ROTI®Phenol.
Addition of 1 volume ROTI®Phenol/Chloroform/Isoamyl alcohol and thorough mixing. Phenol and chloroform lead to denaturation of proteins which accumulate in the interphase. Isoamyl alcohol prevents foaming and very efficiently inhibits RNAses. Following centrifugation, the nucleic acid containing solution may be retrieved as upper phase.
