THE METHOD OF SEPARATING NUCLEOPROTEINS AND NUCLEIC ACIDS FROM OTHER PROTEIN MATERIAL IN ADMIXTURES THEREWITH IN AQUEOUS LIQUID MEDIA, WHICH COMPRISES BRINGING THE AQUEOUS LIQUID INTO INITIMATE ADMIXTURE WITH A LIQUID EXTRACTING AGENT CONSISTING ESSENTIALLY OF A CARBON FLUORINE COMPOUND CONTAINING NO ELEMENTS OTHER THAN CARBON, FLUORINE, HYDROGEN, CHLORINE AND BROMINE, OF THE GROUP CONSISTING OF (1) SATURATED ALIPHATIC AND ALICYCLIC COMPOUNDS CONTAINING FROM 1 TO 4 CARBON ATOMS, AT LEAST 3 HALOGEN ATOMS, AT LEAST 1 FLUORINE ATOM FOR EACH 2 CARBON ATOMS, AND IN WHICH ANY MONOHALOGENATED ALKYL RADICAL IS ALPHA TO A POLYFLUOROSUBSTITUTED CARBON ATOM AND (2) A METHYL BENZENE IN WHICH ALL THE HYDROGENS OF THE METHYL GROUPS ARE PLACED BY FLUORINES, AND THEREAFTER SEPARATING THE MIXED LIQUID INTO A LAYER CONTAINING THE WATER FROM THE AQUEOUS FLUID, WITH THE NUCLEOPROTEIN, NUCLEOTIDE AND NUCLEIC ACID MATERIALS THEREIN, AND A LAYER CONTAINING THE HALOFLUORO HYDROCARBON WITH THE OTHER PROTEINS THEREIN.
