Ethidium bromide has UV absorbance maxima at 300 and 360 nm, and an emission maximum at 590 nm. 2018-08-25 2013-03-05 2008-03-03 Instructions for Use Ethidium bromide is used to visualize DNA in agarose gels and in many cesium chloride gra-dient protocols. The 10 mg/ml ethidium bromide stock solution can be diluted for gel staining or used as provided for CsC1 gradient protocols. Caution: Ethidium bromide is a toxic chemical and a mutagen. It causes eye and skin irritation.

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). 2010-12-16 · Introduced in the 1950s, ethidium bromide (EB) is still used as an anti-trypanosomal drug for African cattle although its mechanism of killing has been unclear and controversial. EB has long been known to cause loss of the mitochondrial genome, named kinetoplast DNA (kDNA), a giant network of interlocked minicircles and maxicircles. 18 Apr 2016 As both these LD50s are many orders of magnitude higher than the concentrations used in molecular biology, toxicity of gel staining solutions is Ethidium Bromide (EtBr, CAS# 1234-45-8) is widely used in biochemical research laboratories for visualizing DNA fragments, and is primarily used on campus Ethidium bromide (EtBr) is commonly used as a non-radioactive marker for identifying and visualizing nucleic acid bands in electrophoresis and in other Ethidium bromide is a sensitive fluorescent stain for visualizing DNA in agarose and polyacrylamide gels. It is excited with a standard 302 nm UV transilluminator 25 Aug 2014 Ethidium Bromide or EtBr is an intercalating agent. EtBr is commonly used to detect nucleic acids inluding double stranded DNA or single The most commonly used stain for detecting DNA/RNA is ethidium bromide.

It both binds to DNA and fluoresces under the Ethidium Bromide (EtBr) Alternatives. Ethidium bromide, long used as an inexpensive, sensitive, and stable dye for staining nucleic acids, is a potent mutagen, 21 Sep 2015 It is also used to treat head and neck cancer. This medication may be used in combination with other medicines or radiation therapy.
