Ethidium bromure 10 mg/ml en solution aqueuse pour l'électrophorèse, Sigma-Aldrich®

Supplier: VWR Chemicals

Fluorescent stain for visualizing nucleic acids.

Supplier: VWR Chemicals

A 10mg/ml solution of Ethidium Bromide in specially prepared deionized water. Ethidium bromide solution is a fluorescent stain for visualising nucleic acids in solution or in electrophoresis gels.

Supplier: VWR Chemicals

Le bromure d'éthidium est fourni dans un flacon compte-gouttes de 0,625 mg/ml. Une goutte diluée dans 50 ml d'agarose fondu ou de tampon donne une concentration finale de 0,5 µg/ml. À une concentration de 0,5 μg/ml, le bromure d'éthidium est utile dans les gels d'agarose ou d'acrylamide pour la détection des bandes. Il sert à détecter des acides nucléiques pouvant atteindre 10 ng. À des concentrations supérieures (0,5 - 1,0 μg/ml), il peut être utilisé pour faciliter la purification de l'ADN dans un gradient de chlorure de césium.

Ethidium bromide(EtBr) has been used extensively to reduce mitochondrial DNA copy number in proliferating cells and most commonly used in 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 has been used in a number of fluorimetric assays for nucleic acids. It has been shown to bind to single-stranded DNA (although not as strongly) and triple-stranded DNA.4 Because of its ability to bind to DNA, EtBr is an inhibitor of DNA polymerase.

A 10mg/mL easy-to-use solution of ethidium bromide in specially filtered, deionized water which is excellent for nucleic acid electrophoresis and purification applications, eliminates the dust hazard associated with powdered ethidium bromide and saves time spent on weighing and mixing. Used in the fluorometric detection of double stranded nucleic acids in gel electrophoresis. Also acts as an RNA polymerase inhibitor, and in separation of high molecular weight DNA's. It confers a deep red stain to DNA by acting as an intercalating agent between the starch bases. Subsequent fluorescence techniques enable the extraction and characterization of DNA bands.

Biochem/physiol Actions:
Ethidium bromide intercalates double-stranded DNA and RNA and acts as a frameshift mutagen. It can also be used in conjunction with acridine orange to differentiate between viable, apoptotic and necrotic cells.
