Inhibition of yeast sporulation by ethidium bromide
Molecular and General Genetics MGG, 1978Ethidium bromide blocks ascus formation in the yeast Saccharomyces cerevisiae. This may mean that the presence of the mitochondrial genome is required for sporulation in this organism.

Renaturation of DNA in the presence of ethidium bromide
Biopolymers, 1972AbstractThe rate of renaturation of T2 DNA has been studied as a fuction of ethidium bound per nucleotide of denatured DNA. The Binding constants and number of binding sites for ethidium have been determined by spectral titration for denatured DNA at 55, 65, and 75°C and for native DNA at 65°C in 0.4M Na+.

An evaluation of the ethidium bromide microcytotoxicity test
Journal of Immunological Methods, 1974Abstract An ethidium bromide fluorescence technique for the demonstration of lymphocytotoxic antibodies is described and evaluated. This fluorescence technique offers the advantages of speed, simplicity, high reproducibility and sensitivity.

Equilibrium studies of ethidium-polynucleotide interactions
Biochemistry, 1981We report equilibrium dialysis studies of the binding of ethidium to a variety of double-helical synthetic polynucleotides containing A.U (or T) and I.C base pairs. The results are interpreted in terms of the neighbor exclusion model of drug binding, with allowance both for cooperativity of binding and for a structural switch of the helix to a ...

Yeast mutants resistant to ethidium bromide
Molecular and General Genetics MGG, 1973Yeast mutants resistant to ethidium bromide have been isolated among sensitive grande cells (ϱ+) for their ability to grow on glycerol in the presence of the dye. Mutant cells are also resistant to acriflavin and do not yield petites (ϱ-) when grown on galactose with the mutagen.

Binding of ethidium bromide to fractionated chromatin
Experimental Cell Research, 1976Abstract The binding of ethidium bromide (EB) to different chromatin preparations was tested. Scatchard plots showed that the slowly sedimenting fraction of sheared chromatin is enriched in dye-binding sites. Limited nuclease digestion of rat liver nuclei, which has been shown to preserve the subunit structure of chromatin, reduces the number of ...
