✦ Synopsis

The absence of DNA from the blood serum of the toad Bufo arenarum was confirmed by classical colorimetric techniques and by a new method which allows differentiation between DNA and the glycosaminoglycans (GAG). A component of serum which had some of the properties of DNA was identified as a GAG. This component gave positive reactions in colorimetric assays for DNA, but the absorption spectra were completely different from those of authentic DNA. The compound was also not hydrolyzed at all by treatment with deoxyribonuclease.
