And Storage

Nucleic acids are routinely and readily analysed using the A260/A280 ratio, although this method is known to be prone to erroneous results owing to contaminants in solution that absorb at similar wavelengths. The aim of the present review, while highlighting the problems and alternatives of using UV spectrophotometry for nucleic acid measurements, is to bring forth an observational result from our recent studies, namely that DO (dissolved oxygen) and nitrogen can alter the A260 of aqueous DNA solutions. Our finding is of importance because DO is highly variable between protocols and storage conditions of DNA preparations. The physicochemical nature of the oxygen–DNA interactions is briefly discussed.

Labeled Rna

Ribonucleic acids labeled with 14C- or 3H-orotic acids, respectively were extracted from aliquots of mouse liver homogenates according to the cold-phenol-method of Kirby or the method of Georgiev employing different temperature steps.This comparative analysis showed that only ca. 50% of the total labeled RNA was extracted by the Kirby method. Especially the high molecular D-RNA and R-RNA were not sufficiently extracted, as was demonstrated by hydroxyapatite- and methylalbumin-Kieselgur column chromatography.Reextraction of the tissue at 65 °C first extracted by the Kirby method resulted in a recovery of most of the missing nucleic acid species.Therefore, results obtained by the Kirby and Georgiev methods will be different in regard to the nucleic acid composition. These findings could explain contradictary results about this problem in literature.

Calcium phosphate co-precipitates half its mass of ribonucleic acids made from yeast, tobacco leaf and tobacco mosaic virus when the precipitate is formed in their presence. It also precipitates deoxyribonucleic acid. Degraded nucleic acids are less completely precipitated. Less nucleic acid is adsorbed by preformed calcium phosphate. In suitable circumstances nucleic acid is fixed by leaf fibre. Autolytic changes in leaf fibre, and in calcium-chelators in leaf extracts, explain many differences in the amount of nucleic acid present in extracts made from tobacco leaves in different ways.
