pubmed-article:1616721pubmed:abstractTextA fluorometric procedure for the detection of DNA-DNA hybrids is described. The procedure involved the detection of probe-bound alkaline phosphatase with the fluorescent substrate ATTOPHOS. This substrate is converted to ATTOFLUOR by alkaline phosphatase and fluoresces strongly at 550 nm when excited with a wavelength of 440 nm. DNA hybridization assays were performed both with dilutions of purified target plasmid DNA (pSE9 or PBR322) and whole bacterial cells. Streptavidin-alkaline phosphatase conjugates were added to react with bound probe. Fluorometric assays, as well as colorimetric assays, using 5-bromo-4-chloro-3-indolylphosphate + nitroblue tetrazolium for alkaline phosphatase activity were performed. The fluorescence of the substrate was measured at time intervals, and the slope of the regression line calculated. A slope four times greater than that of background was considered positive. One hundred femtograms or 2.2 x 10(4) molecules of homologous DNA were detected with the fluorescent assay as compared with 10,000 femtograms or 2.2 x 10(6) molecules of homologous DNA with the colorimetric assay. Similar results were obtained with whole cells. Approximately 1 x 10(3) homologous cells were detected fluorometrically and 1 x 10(5) cells were detected colorimetrically. Based on these results, we conclude that, in our hands, the DNA hybridization assay described here using ATTOPHOS as the substrate for alkaline phosphatase is a very sensitive assay for the detection of DNA-DNA hybrids.lld:pubmed
