Brometo de etídio

Descrição:
Brometo de etídio é um agente intercalante fluorescente comumente usado em biologia molecular para a detecção de ácidos nucleicos em técnicas como eletroforese em gel. Possui uma fórmula molecular de C21H20BrN3 e um peso molecular de aproximadamente 394,31 g/mol. Brometo de etídio aparece como um pó laranja-avermelhado e exibe forte fluorescência quando ligado ao DNA, emitindo luz no espectro laranja quando exposto à luz ultravioleta (UV). Seu mecanismo de ação envolve a intercalacão entre os pares de bases do DNA, o que permite a visualização de ácidos nucleicos em géis de agarose. Embora seja eficaz para aplicações de laboratório, Brometo de etídio é considerado perigoso devido às suas propriedades mutagênicas e potenciais riscos à saúde quando exposto, exigindo manuseio e descarte cuidadosos. É solúvel em água e solventes orgânicos, tornando-o versátil para várias configurações experimentais. Devido à sua toxicidade, alternativas mais seguras são frequentemente buscadas em laboratórios modernos, mas Brometo de etídio continua sendo um elemento básico em muitos protocolos tradicionais.

  • Ethidium bromide

    CAS:
    <p>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.</p>

    CAS:
    <p>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).
