WebEthidium bromide (EtBr) is a flat molecule that fits between adjacent base pairs (intercalates) in the DNA double helix. It has UV absorbance maxima at 300 and 360nm, and can also absorb energy from nucleotides excited at 260nm. The absorbed energy is emitted as orange/yellow light at 590nm. Web10 feb. 2024 · As DNA is not visible to the naked eye, an intercalating dye such as ethidium bromide (EtBr) is incorporated in the gel during setting. This binds the DNA and fluoresces under UV light, allowing the DNA fragments to be visualized. The more DNA present, the brighter the band.
