EtBr acts as an intercalating agent, which binds to the DNA strands and emits a fluorescent sign when uncovered to an ultraviolet (UV) mild supply. This makes it attainable to detect bands of DNA on an agarose gel. On account of its carcinogenic properties, particular precautions have to be taken when dealing with Ethidium bromide. It is strongly recommended that protecting gloves and eye safety be worn when dealing with EtBr.
