Dec 2, 2002 Ethidium bromide is a cationic dye that is widely used as a probe for native DNA. The ethidium ion displays a dramatic increase in fluorescence
Ethidium bromide helps to identify DNA fragments, products of its enzymatic degradation that can be used in the PCR technique. Agarose and acrylamide gel electrophoresis of DNA. The ethidium bromide is incorporated into the gel prior to performing the electrophoresis.
Formaldehyd 37 %. >480 min. 6. Gluteraldehyde 50 %. >480 min.
Despite extensive studies of ethidium bromide complexes with polynucleotides, a satisfactory mechanism explaining the high degree of fluorescence enhancement upon binding has not A trypanocidal agent and possible antiviral agent that is widely used in experimental cell biology and biochemistry. Ethidium has several experimentally useful properties including binding to nucleic acids, noncompetitive inhibition of nicotinic acetylcholine receptors, and fluorescence among others. It is most commonly used as the bromide. 2007-09-26 Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis. Ethidium bromide (EtBr) is the most commonly used nucleic acid stain for PAGE or agarose gel electrophoresis. The fluorescence of EtBr increases 21-fold upon binding to double-stranded RNA and 25-fold on binding double-stranded DNA so that destaining the background is not necessary with a low stain concentration (10 μg/ml). Ethidium bromide is a valuable aid for visualizing DNA in gels, but it is considered a “powerful mutagen with moderate toxicity” (MacGregor and Johnson, 1977).

Single-stranded RNA can also be detected, since it usually folds back onto itself and thus provides local base pairing for the dye to intercalate. What is ethidium bromide? Molecular Biology-grade Powder (Product No. E7637) is suitable for use in gel electrophoresis and DNA isolation Aqueous Solution (10 mg/mL) (Product No. E1510) is suitable for use in gel electrophoresis and DNA isolation procedures. Molecular Biology-grade Aqueous Se hela listan på ehs.research.uiowa.edu Se hela listan på sciencedirect.com Ethidium bromide is a DNA intercalator, inserting itself between the base pairs in the double helix. Ethidium bromide has UV absorbance maxima at 300 and 360 nm, and an emission maximum at 590 nm. The detection limit of DNA bound to ethidium bromide is 0.5 to 5.0 ng/band. 2016-04-18 · Ethidium bromide is found in pretty much every molecular biology lab around.
