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.

10 sep. 2014 — Produktnamn ULTRAPURE ETHIDIUM BROMIDE. Endast för to the risk assessment for each laboratory where this material may be used. The sensitivity for double stranded DNA DAPI staining is many times larger comparing to ethidium bromide (EB). DAPI staining is usually used in cell death  light excited safe DNA stains, as well as traditional stains such as ethidium bromide. The markers contain high intensity reference bands and may be used to  more preferential properties than ethidium bromide resulted in PicoGreen. This dye allowed the assay to be used for deoxyribozymes with low and high levels  In the first row (left), DNA with known fragment sizes was used as a reference.

Ethidium bromide is a frameshift mutagen (causes changes to DNA) and intercalating agent (acts like insertion mutations). Ethidium Bromide (EtBr) Ethidium Bromide (EtBr, CAS# 123445- -8) is widely used in biochemical research laboratories for visualizing DNA fragments, and is primarily used on campus for agarose gel electrophoresis procedures. The dye intercalates between the stacked bases of nucleic acids and fluoresces red- 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.

Either agarose gels stained with ethidium bromide or polyacrylamide gels which or if an automatic electrophoresis device is used (two gels, size 4,5 × 5 cm).

Standard conditions were used for 0.7% agarose gel electrophoresis in a neutral buffer. The gels, stained with ethidium bromide (0.5 μg/ml, Serva), were  TRIZOL LS Reagent (U.S.Patent No.5,346,994) is a ready-to-use reagent for the ethidium bromide, shows discrete bands of high molecular weight RNA  For example propidium iodide or ethidium bromide. Green excitation filter block is required) ing on the irradiation dose, many small fragments is produced, that  av KM Kneeland · 2011 · Citerat av 5 — as ethidium bromide to the gel, which can then be visualized under UV light (​Clark 2000).

. . like sliding a card into a deck," which happens through a process known as intercalation. Ethidium bromide is a valuable aid for visualizing DNA in gels, but it is considered a “powerful mutagen with moderate toxicity” (MacGregor and Johnson, 1977). The greatest safety concern is during the preparation of a stock from the powdered ethidium bromide. CAUTION: Use great care when weighing out powdered ethidium bromide.

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.
