  2. Ethidium bromide - Wikipedia

    en.wikipedia.org/wiki/Ethidium_bromide

    Absorption spectrum of ethidium bromide. As with most fluorescent compounds, ethidium bromide is aromatic. Its core heterocyclic moiety is generically known as a phenanthridine, an isomer of which is the fluorescent dye acridine. Absorption maxima of EtBr in aqueous solution are at 210 nm and 285 nm, which correspond to ultraviolet light.

  3. Gel electrophoresis of nucleic acids - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis_of...

    Once the nucleic acid is properly prepared, the samples of the nucleic acid solution are placed in the wells of the gel and a voltage is applied across the gel for a specified amount of time. The DNA fragments of different lengths are visualized using a fluorescent dye specific for DNA, such as ethidium bromide. The gel shows bands ...

  4. Agarose gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Agarose_gel_electrophoresis

    The ethidium bromide may be added to the agarose solution before it gels, or the DNA gel may be stained later after electrophoresis. Destaining of the gel is not necessary but may produce better images.

  5. Gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis

    DNA may be visualized using ethidium bromide which, when intercalated into DNA, fluoresce under ultraviolet light, while protein may be visualised using silver stain or Coomassie brilliant blue dye. Other methods may also be used to visualize the separation of the mixture's components on the gel.

  6. Electrophoretic color marker - Wikipedia

    en.wikipedia.org/wiki/Electrophoretic_color_marker

    The most commonly used dye in agarose gel gel electrophoresis of DNA and RNA, dating as far back as the 1970s, is ethidium bromide (2,7-diamino-10-ethyl-9-phenylphenanthridiniumbromide). [citation needed] Ethidium Bromide (EtBr) is an orange-colored fluorescent intercalating

  7. Intercalation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Intercalation_(biochemistry)

    The degree of unwinding varies depending on the intercalator; for example, ethidium cation (the ionic form of ethidium bromide found in aqueous solution) unwinds DNA by about 26°, whereas proflavine unwinds it by about 17°. This unwinding causes the base pairs to separate, or "rise", creating an opening of about 0.34 nm (3.4 Å).

  9. Bromoethane - Wikipedia

    en.wikipedia.org/wiki/Bromoethane

    Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.
