Protection of proteins against denaturation by fluorinated aliphatic compounds

Claim 1

A METHOD FOR PROTECTING PROTEINACEOUS MATERIALS FROM HEAT AND CHEMICAL DENATURATION COMPRLISING: FORMING AN AQUEOUS SOLUTION OF A WATER SOLUBLE PROTEINACEOUS MATERIAL; ADDING TO SAID SOLUTION A FLUORO COMPOUND SELECTED FROM THE GROUP CONSISTING OF PERFLUOROALKANOIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, OMEGAHYDROPERIFLUOROALKANOIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, CHLOROPERFLUOROALKANOIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, ALPHA-DIHYDROPERFLUOROALKANOLS CONTAINING FROM 2 TO 12 CARBON ATOMS, FLUOROALKYL SULFONATES CONTAINING FROM 2 TO 12 CARBON ATOMS, FLUOROALKYL SULFATES CONTAINING FROM 2 TO 12 CARBON ATOMS, FLUOROALKYL SULFONIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, ALPHA-DIHYDROPERFLUOROALKYL AMINES CONTAINING FROM 2 TO 12 CARBON ATOMS, ALKALI METAL AND AMMONIUM MONO- AND DI-(TRIHYDROPERFLUOROALKYL) PHOSPHATES, THE ALKALI METAL AND AMMONIUM SALTS OF SAID ACIDS, ALCOHOLS AND SULFONATES, AND THE HYDROCHLORIDE, HYDROBROMIDE, SULFATE AND PHOSPHATE SALTS OF SAID AMINES; AND ADJUSTING THE PH OF SAID SOLUTION SO THAT THE NET IONIC CHARGE ON THE PROTEINACEOUS MATERIAL IS OF THE SAME SIGN AS THE CHARGE ON THE FLUORO CONTAINING ION FORMED IN SOLUION BY THE FLUORO COMPOUND, WHEREBY TH FLUORO COMPOUND IS BOUND TO SAID PROTEINACEOUS MATERIAL AND A SOLUTION OF A FLUORO COMPOUND-PROTEIN COMPLEX IS FORMED.

Claim 2

A METHOD FOR PROTECTING PROTEINACEOUS MATERIALS FROM HEAT AND CHEMICAL DENATURATION COMPRLISING: FORMING AN AQUEOUS SOLUTION OF A WATER SOLUBLE PROTEINACEOUS MATERIAL; ADDING TO SAID SOLUTION A FLUORO COMPOUND SELECTED FROM THE GROUP CONSISTING OF PERFLUOROALKANOIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, OMEGAHYDROPERIFLUOROALKANOIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, CHLOROPERFLUOROALKANOIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, ALPHA-DIHYDROPERFLUOROALKANOLS CONTAINING FROM 2 TO 12 CARBON ATOMS, FLUOROALKYL SULFONATES CONTAINING FROM 2 TO 12 CARBON ATOMS, FLUOROALKYL SULFATES CONTAINING FROM 2 TO 12 CARBON ATOMS, FLUOROALKYL SULFONIC ACIDS CONTAINING FROM 2 TO 12 CARBON ATOMS, ALPHA-DIHYDROPERFLUOROALKYL AMINES CONTAINING FROM 2 TO 12 CARBON ATOMS, ALKALI METAL AND AMMONIUM MONO- AND DI-(TRIHYDROPERFLUOROALKYL) PHOSPHATES, THE ALKALI METAL AND AMMONIUM SALTS OF SAID ACIDS, ALCOHOLS AND SULFONATES, AND THE HYDROCHLORIDE, HYDROBROMIDE, SULFATE AND PHOSPHATE SALTS OF SAID AMINES; AND ADJUSTING THE PH OF SAID SOLUTION SO THAT THE NET IONIC CHARGE ON THE PROTEINACEOUS MATERIAL IS OF THE SAME SIGN AS THE CHARGE ON THE FLUORO CONTAINING ION FORMED IN SOLUION BY THE FLUORO COMPOUND, WHEREBY TH FLUORO COMPOUND IS BOUND TO SAID PROTEINACEOUS MATERIAL AND A SOLUTION OF A FLUORO COMPOUND-PROTEIN COMPLEX IS FORMED.
