Careful handling and stringent controls of Ethidium bromide is essential in order to protect workers and the environment, and to comply with OSHA regulations. 2. Additional safety requirements may apply, depending on if Ethidium bromide is mixed/used with a specific chemical. Ethidium bromide binds to DNA through non covalent Vander Waal interactions with DNA base pairs and is fluorescent at the ultra-violet wavelength of light.

When used for the staining of fixed tissue sections, the dye stains cellular nuclei with excellent resolution of microscopic det … Ethidium bromide is a molecule commonly used to visualize DNA in agarose gel electrophoresis experiments. It both binds to DNA and fluoresces under the proper conditions. Ethidium bromide is known as an intercalating agent. The flat structure of ethidium bromide allows it to intercalate, or insert, between nitrogenous bases of a DNA molecule. This interaction is especially useful because of Ethidium bromide is the most commonly used dye for DNA and RNA detection in gels. Ethidium bromide is a DNA intercalator, inserting itself between the base pairs in the double helix. Ethidium bromide has UV absorbance maxima at 300 and 360 nm, and an emission maximum at 590 nm.

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.

Ethidium bromide (EB), an intercalating drug, has been shown to prevent the in vitro interaction of the estrogen receptor (R) with DNA. We have now studied the effect of this drug on the nuclear translocation of R in order to determine whether DNA integrity is needed for this translocation. Ethidium Bromide Waste Management Bulletin A new Standard Operating Procedure for ethidium bromide use and disposal was completed and introduced at Departmental/School Laboratory Safety Committees in 2010. This Bulletin describes the policy change and how it affects the way you manage your ethidium bromide waste. Overview more expensive) option is to use a blue light box as the wavelengths used do not cause DNA . damage. UV-transilluminators can also be used, although specific filters may be required.

Molecular methodsQIAamp® DNA Micro kit was used by the instructions for by electrophoresisin a 1 % agarose gel with ethidium bromide (∼0.8 µl/ml).
