Interaction of Ethidium Bromide with Heparin

International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1975
The 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.

A synthesis of labeled ethidium bromide

Archives of Biochemistry and Biophysics, 1974
Abstract 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 ...

Yeast mutants resistant to ethidium bromide

Molecular and General Genetics MGG, 1973
Yeast 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.

Synthesis of 6-14C-ethidium bromide

Analytical Biochemistry, 1972
Abstract 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.
