Abstract
OWING to the content of purine and pyrimidine rings of the nucleic acids, they exhibit a specific absorption within the ultra-violet range with an absorption maximum at 2600 A. This makes it possible to demonstrate directly the presence of nucleotides in cells. The quantitative conditions can be studied by means of the technique devised by Caspersson and co-workers. A method has now been worked out in which the order of magnitude of the nucleotide content in bacteria can be determined by photometry of microphotographs taken at 2570 A.
