Inhibition of yeast sporulation by ethidium bromide
Molecular Genetics and Genomics, 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.

Ethidium bromide enhancement of frameshift mutagenesis caused by photoactivatable ethidium analogs
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1979Ethidium azide analogs (3-amino-8-azido-ethidium monoazide and ethidium diazide) have been developed as photosensitive probes in order to analyze directly the reversible in vivo interactions of ethidium bromide. Our preliminary observations [11], relating the mutagenic potential of the monoazide analog of ethidium, have been extended and refined, using

A synthesis of labeled ethidium bromide
Archives of Biochemistry and Biophysics, 1974Abstract A method is described for the synthesis of labeled ethidium (3,8-diamino-5-ethyl-6-phenyl phenanthridinium) bromide. Based on benzoic acid, the radioactive precursor used, the yield is 15% of a compound that is indistinguishable from authentic ethidium bromide in its absorption spectra (uv, visible, ir), Chromatographie behavior, and ...

Interaction of Ethidium Bromide with Heparin
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1975The reactions of hydrated electrons produced during pulse radiolysis have been utilized to investigate the binding of ethidium bromide to heparin. Complexes of ethidium bromide and heparin can be dissociated with salt. Divalent cations are more effective than monovalent cations in this respect.

Mitochondrial membranes and mutagenesis by ethidium bromide
Journal of Supramolecular Structure, 1972AbstractThe conversion of wild type (ρ+) to cytoplasmic petites (ρ−) in Saccharomyces cerevisiae, à mutation in mitochondrial DNA, can be brought about with high efficiency by low concentrations of ethidium bromide (EB). The rate and extent of mutagenesis and its expression can be influenced, and even reversed, by a number of genetic lesions, agents or

Staining of Nuclei in Fungi by Ethidium Bromide
Biotechnic & Histochemistry, 1991Ethidium bromide, (0.1% solution in ethanol-water, 1:3, v/v) was used to stain nuclei in mycelia and spores of different fungi. Nuclei looked bright brick red under green excitation. This method is very efficient, specific, reproducible and cost-effective.

Synthesis of 6-14C-ethidium bromide
Analytical Biochemistry, 1972Abstract The preparation of 6- 14 C-ethidium bromide of high specific radioactivity is described. The synthesis starts from 14 C-carboxyl-labeled benzoic acid and 4,4′-dinitro-2-aminodiphenyl. The crude compound was purified by chromatography on aluminum oxide.

Multiple interactions of ethidium bromide with yeast cells
Archives of Biochemistry and Biophysics, 1980Abstract Experiments were carried out to determine the relationship between different energy states of the yeast cell and the uptake of ethidium bromide (EB). By varying the substrate, oxygenation, and by the use of uncouplers or respiratory inhibitors, it is possible to have energization or not of the whole cell, and also to deenergize specifically ...
