IMPROVED TECHNIQUES FOR THE ENZYMATIC EXTRACTION OF NUCLEIC ACIDS FROM TISSUE SECTIONS

Since the removal of only one of the two nucleic acids, ribonucleic and deoxyribonucleic, is often necessary in biological work, the optimum conditions for the specific removal of either nucleic acid by the corresponding enzyme were investigated. The specific removal of nucleic acids by enzyme treatment was tested by toluidine blue staining and by quantitative study of the radioautographic reactions produced by the labelled deoxyribonucleic acid...
