Abstract

PURPOSE: To obtain ribonucleic acid free from alkaline earth metals, by mixing ribonucleic acid with alkali matal carbonate or ammonium carbonate and water, reacting the components under slightly alkaline conditions, and removing the produced precipitate.
CONSTITUTION: Ribonucleic acid is mixed with one or more compounds selected from alkali metal carbonates and ammonium carbonate, and water, the pH of the mixture is adjusted to slightly alkaline state, pref. 9W10pH, and the components are reacted with each other at 30W40°C. The alkaline earth metal in the ribonucleic acid is exchanged with alkali metal or ammonia, and is precipitated as the carbonate. If necessary, the pH of the solution is adjusted to neutral, and the precipitate is removed by filtration, centrifugal separation, etc.
