We did a lab with DNA standards. We made one to one solutions of onion DNA which we precipitated and a 4% NaCl solution. We measured the amount of DNA by using spectrophotometers. When we boiled the solution before measurement, the NaCl precipitated. This made the solution cloudy and the absorbance readings inaccurate.

I am wondering if there could be another solution which could be used to make the one to one solution, such as distilled water, or if the NaCl solution has a special role in the ionization?
