The use of ammonium acetate in the precipitation of ribonucleic acid

Abstract
Ammonium acetate (0.24M) in combination with cold 66% (v/v) ethanol quantitatively precipitated RNA from very dilute solutions (greater than or equal to mug/ml) after centrifugation for 2.5 X 10(6)g-min. There was also less co-precipitation of detergents with ammonium acetate than NaCl.
