WebAdd 1/10 volume of 3 M Na-Acetate pH 5.2, and 2 to 2.5 volumes of ice-cold 100% ethanol to the DNA sample; Mix, and store at –20°C for at least 1 h to precipitate the DNA; Recover the precipitated DNA by centrifugation at full speed in a microcentrifuge for 15–20 min; Pour off the ethanol and wash the pellet twice with room-temperature 70% ... WebDNA is less soluble in isopropanol so it precipitates faster even at low concentrations. The downside however is that salt will also precipitate in isopropanol. With ethanol, the DNA needs to be at a higher concentration to flocculate but the salt tends to stay soluble, even at colder temperatures. DNA precipitates in 35% isopropanol and 0.5 M ...
