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 ...

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.

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

Ethidium bromide mutagenesis in yeast: Protection by anaerobiosis
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1975The mutagenesis by ethidium bromide, an intercalating dye, which induces the mutation from wild type (rho+) to the cytoplasmic respiratory deficient petite (rho-) in Saccharomyces cerevisiae, was studied under aerobic and anaerobic conditions. During growth of anaerobic cells at pH 6.5, ethidium bromide at a concentration of 2 mug/ml is unable to ...

Binding of ethidium bromide to avian erythrocyte chromatin
Biochemical and Biophysical Research Communications, 1972Summary Ethidium bromide intercalation studies indicate that mature avian erythrocyte chromatin has 5.6 times fewer primary binding sites than deproteinized DNA. The number of both primary and secondary binding sites was increased upon removal of chromosomal proteins; among those, removal of avian erythrocyte specific histone V shows the highest ...

Binding of ethidium bromide to liver glutamate dehydrogenase
Biochemical and Biophysical Research Communications, 1976Abstract Liver glutamate dehydrogenase forms a complex with ethidium bromide in solution; binding parameters of this complex depend on pH and enzyme concentration, but are independent of the ionic strength of solution. Binding of ethidium bromide occurs outside the coenzyme binding site, but appears to be closely related to the oligomer association ...

Conditions that prevent ϱ−-induction by ethidium bromide
Biochemical and Biophysical Research Communications, 1971Abstract The rate of petite induction of an adenine-requiring Saccharomyces cerevisiae was strongly inhibited by the presence of 10% glucose or nalidixic acid (500 μg/ml) during the incubation in minimal medium + adenine + 0.5% glucose + ethidium bromide.

A yeast mitochondrial deoxyribonuclease stimulated by ethidium bromide
Biochemical and Biophysical Research Communications, 1972Abstract Several DNase activities, with different substrate and pH requirements, have been identified in yeast mitochondria. One of them is active on double stranded DNA at neutral pH and stimulated by Ethidium Bromide and other DNA intercalating drugs.

Fluorescent Staining of Hair Cells with Ethidium Bromide
Acta Oto-Laryngologica, 1978The present study evaluated ethidium bromide, a nucleic acid-specific fluorescing stain for cochlear applications. Tissue exposed to acoustic stimulation did not exhibit the loss of fluorescence in hair cells described in studies on other fluorescing stains.
