Ethidiumbromid

Beschreibung:

Ethidiumbromid ist ein fluoreszierendes interkalierendes Mittel, das häufig in der Molekularbiologie zur Detektion von Nukleinsäuren in Techniken wie der Gelelektrophorese verwendet wird. Es hat eine chemische Formel von C21H20BrN3 und ein Molekulargewicht von etwa 394,31 g/mol. Ethidiumbromid erscheint als ein orange-rotes Pulver und zeigt eine starke Fluoreszenz, wenn es an DNA gebunden ist, und emittiert Licht im orangefarbenen Spektrum bei Bestrahlung mit ultraviolettem (UV) Licht. Sein Wirkmechanismus besteht darin, sich zwischen den Basenpaaren der DNA zu interkalieren, was die Visualisierung von Nukleinsäuren in Agarosegelen ermöglicht. Obwohl es für Laboranwendungen effektiv ist, gilt Ethidiumbromid aufgrund seiner mutagenen Eigenschaften und potenziellen Gesundheitsrisiken bei Exposition als gefährlich, was eine sorgfältige Handhabung und Entsorgung erforderlich macht. Es ist in Wasser und organischen Lösungsmitteln löslich, was es vielseitig für verschiedene experimentelle Setups macht. Aufgrund seiner Toxizität werden in modernen Laboren oft sicherere Alternativen gesucht, aber Ethidiumbromid bleibt ein Grundpfeiler in vielen traditionellen Protokollen.

Applications 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.
Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package

Ethidium bromide

CAS: 1239-45-8

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.
