:Bromure d'éthidium
Description :
Bromure d'éthidium est un agent intercalant fluorescent couramment utilisé en biologie moléculaire pour la détection des acides nucléiques dans des techniques telles que l'électrophorèse sur gel. Il a une formule moléculaire de C21H20BrN3 et un poids moléculaire d'environ 394,31 g/mol. Bromure d'éthidium apparaît sous forme de poudre rouge-orange et présente une forte fluorescence lorsqu'il est lié à l'ADN, émettant de la lumière dans le spectre orange lorsqu'il est exposé à la lumière ultraviolette (UV). Son mécanisme d'action implique l'intercalation entre les paires de bases de l'ADN, ce qui permet la visualisation des acides nucléiques dans les gels d'agarose. Bien qu'efficace pour les applications de laboratoire, Bromure d'éthidium est considéré comme dangereux en raison de ses propriétés mutagènes et des risques potentiels pour la santé en cas d'exposition, nécessitant une manipulation et un élimination prudentes. Il est soluble dans l'eau et les solvants organiques, ce qui le rend polyvalent pour divers montages expérimentaux. En raison de sa toxicité, des alternatives plus sûres sont souvent recherchées dans les laboratoires modernes, mais Bromure d'éthidium reste un élément de base dans de nombreux protocoles traditionnels.

CAS :Produit contrôléApplications 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 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. Because of its ability to bind to DNA, EtBr is an inhibitor of DNA polymerase. Antiprotozoal (Trypanosoma). Dyes and metabolites.

CAS :Ethidium bromide is a natural compound that is used as a fluorescent dye. The dye binds to the nucleic acids of the cell, including DNA and RNA, which intercalate with the guanine residues in the DNA. The dye molecules fluoresce when excited by ultraviolet light. This property has been used for biochemical research on nucleic acids and for labeling cells in histological sections for electron microscopy. Ethidium bromide has also been used in rat hippocampal neurons to study nicotinic acetylcholine receptor function.Formule :C21H20N3·BrDegré de pureté :Min. 98 Area-%Couleur et forme :Red Purple PowderMasse moléculaire :394.31 g/molRef: 3D-FE10537
