Ethidium bromide is a nucleic acid stain used in agarose gel electrophoresis and PAGE. It’s also a DNA polymerase inhibitor. Ethidium bromide binds to single-stranded and triple-stranded DNA, which inhibits DNA polymerase. It’s also an antiprotozoal and fluorescent label for DNA.
Ethidium bromide (EtBr) is a non-radioactive marker used to stain DNA. It’s commonly used in molecular biology laboratories to detect nucleic acids, such as double-stranded DNA from PCRs and restriction digests.
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. Wikipedia
