Bromuro di etidio

Descrizione:

Bromuro di etidio è un agente intercalante fluorescente comunemente usato in biologia molecolare per la rilevazione degli acidi nucleici in tecniche come l'elettroforesi su gel. Ha una formula molecolare di C21H20BrN3 e un peso molecolare di circa 394,31 g/mol. Bromuro di etidio appare come una polvere rosso-arancione ed espone una forte fluorescenza quando legato al DNA, emettendo luce nello spettro arancione quando esposto a luce ultravioletta (UV). Il suo meccanismo d'azione implica l'intercalazione tra le coppie di basi del DNA, il che consente la visualizzazione degli acidi nucleici nei gel di agarosio. Sebbene sia efficace per applicazioni di laboratorio, Bromuro di etidio è considerato pericoloso a causa delle sue proprietà mutagene e dei potenziali rischi per la salute in caso di esposizione, richiedendo un'attenta manipolazione e smaltimento. È solubile in acqua e solventi organici, rendendolo versatile per vari allestimenti sperimentali. A causa della sua tossicità, spesso si cercano alternative più sicure nei laboratori moderni, ma Bromuro di etidio rimane un elemento fondamentale in molti protocolli tradizionali.

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.

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
