Ethidium bromide is a potent mutagen, often used in laboratories to stain nucleic acids in electrophoresis gels. Ethidium bromide is not a regulated hazardous material, but due to its potential health hazards, precautions should be taken during handling and disposal. (E) Ethidium bromide modifies the agarose electrophoretic mobility of CAG•CTG products generated by bulk PCR amplification of 20–100 ng of template genomic DNA. Ethidium bromide post-staining revealed slow migrating DNA species containing 56 and 200 CAG•CTG repeats, which were undetected when the dye was added to the gel and running buffer. The effects of ethidium bromide induced loss of mitochondrial DNA on mitochondrial phenotype and ultrastructure in a human leukemia T-cell line (MOLT-4 cells). Toxicol Appl Pharmacol. 2004;196(1):68–79.

The mode of binding of EtBr is intercalation between the base pairs. Ethidium bromide, propidium iodine (PI) and 7- amino-actinomycin D (7-AAD) are three red fluorescent dyes that intercalate into DNA of membrane-damaged cells (Fig. 11).Ethidium bromide is considered carcinogenic, that is the reason why it is currently less used. PI and 7-AAD are both excited at 488 nm but the emission range(625 nm for PI and 655 nm for 7-AAD 655 nm), makes the difference, PI Ethidium bromide is the most commonly used dye for DNA and RNA detection in gels.

184 PMA was shown to work better compared with EMA, due to its higher molecular charge (two positive charges in PMA compared with one positive charge in EMA). 184 The higher molecular charge provides greater impermeability through intact cell membranes, thus Several investigators have described the ultrastructural changes that occur in the mitochondria of cells in tissue cultures after treatment with the drug ethidium bromide (E). The mitochondria swell and the cristae become greatly altered and finally disappear; in the cristae-free region of the matrix electron-dense granules can be observed.

The fluorescence of ethidium monoazide is weak, but the intensity increases ~15-fold on binding to DNA with excitation/emiss Ethidium bromide is an intercalating agent commonly used as a fluorescent tag in molecular biology laboratories for techniques such as agarose gel electrophoresis. It is commonly abbreviated as EtBr, which is also an abbreviation for bromoethane.

Diese werden mit Ethidiumbromid angefärbt. Sowohl SYBR Safe als auch Ethidiumbromid stellen kein Problem für das Gerät Fas-V dar. Was wir persönlich an dieser Technologie so toll finden ist zum einen, dass das Blau-Grünlicht kaum die DNA schädigt und zum anderen, dass es nicht gefährlich für die eigene Person ist.
