WebApr 10, 2024 · 2.3.1 Ethanol precipitation. 15 mL of filtrate was used for the isolation of dissolved DNA using ethanol precipitation. Samples were thawed, and 1.2 mL of 5 M sodium chloride and 33 mL of absolute ethanol (200-proof) were added to the tube. The tube was vortexed and incubated overnight at −20°C. DNA is polar due to its highly charged phosphate backbone. Its polarity makes it water-soluble (water is polar) according to the principle "like dissolves like". Because of the high polarity of water, illustrated by its high dielectric constant of 80.1 (at 20 °C), electrostatic forces between charged particles are considerably lower in aqueous solution than they are in a vacuum or in air.
