Dissociation of nucleoprotein complexes by chaotropic salts

Abstract
The effect of various anions in destabilizing yeast nucleoprotein complexes followed the order F < Cl < Br < ClO 4 ⋍ Cl3CCOO. Treatment of yeast nucleoproteins with 0.5 M NaClO4 resulted in removal of 80% of RNA. Based on the results, a simple method for effective separation of RNA from ribosomal particles is proposed and the mechanism of RNA dissociation by anions is also discussed.
