Ethanol precipitation is a commonly used technique for concentrating and de-salting nucleic acids (DNA or RNA) preparations in aqueous solution. The basic procedure is that salt and ethanol are added to the aqueous solution, which forces the precipitation of nucleic acid nucleic acids out of solution.he idea is that for most solvents, including ethanol, the solubility (i.e. the amount of solute they can hold) decreases with temperature. So by lowering the temperature, you theoretically lower the amount of DNA that the ethanol can hold in solution.
