Acetone is an extremely flammable chemical. It has a boiling point  of 56.53 degrees Celsius. It has a very low melting point.
This is commonly achieved by adding a water-soluble solvent such as acetone to an aqueous solution of protein. Acetone had the advantage that it is relatively inexpensive and is available in in a pure form with few contaminants that may inhibit or poison the enzyme. It is also frequently used in sterol extraction.n practice, it is routinely carried out at a temperature below 0ÂºC. Questions Calculate the volume fraction of acetone at the onset of precipitation for each protein solution. Calculate the protein yield for each case by following the same procedure as in ammonium sulfate precipitation.
