โฆ Synopsis
A simple, reproducible fluorescent assay has been described which can be used confidently at microgram and submicrogram levels. The method is most suitable for cell cycle and cell growth analysis using [3H]thymidine as the radioactive tracer. A modified method is also described for preparing diaminobenzoic acid hydrochloride.

The validation of a simple and rapid DNA solubilization procedure is described. Quantitative extraction of intact, polymerized DNA was achieved by cell lysis or tissue homogenization in an ammonium hydroxide-Triton X-100 solution. The solubilization procedure inactivates endogenous DNAase and increa
The diaminobenzoic acid dihydrochloride fluorescence method has been examined to determine optimal conditions for the assay of DNA in perchloric acid extracts and in pretreated Chlamydomonas cells on glass-fiber filters. Maximal fluorescence yield was obtained by allowing: (a) the perchloric acid ex
