[68] Preparation of bacterial DNA by the phenol-pH 9-RNases method

open access: closed, 1967
Publisher Summary This chapter describes the method for the extraction of DNA from bacterial cells using phenol. Phenol treatment is considered one of the most effective methods for deproteinization. Whereas a neutral or acidic buffer (pH 5-7) extracts RNA into aqueous phase, rather than DNA from bacterial cells, in phenol treatment slightly alkaline

Processing yeast to reduce its nucleic acid content. Induction of intracellular RNase action by a simple heat‐shock procedure, and an efficient chemical method based on extraction of RNA by salt solutions at low pH

open access: closedJournal of the Science of Food and Agriculture, 1978
AbstractAutolytic breakdown of the RNA of Saccharomyces cerevisiae can be induced by subjecting a suspension of yeast in NaCl solution at pH 6 to heat shock, produced by bringing the suspension to 50°C and then adding enough water at 100°C to increase the temperature momentarily to 68°C, followed after 1 min by the addition of cold water to reduce it ...
