Synonyms: EtBr 3,8-Diamino-5-ethyl-6-phenylphenanthridinium bromide Homidium bromide . This is believed to block or trip biological .

The main portion of the molecule is a tricyclic structure with Liquid ethidium bromide and buffer containing ethidium . Hence ethidium bromide is a mutagen, suspected carcinogen and at high concentrations is irritating to the eyes, skin, mucous membranes and upper respiratory tract. Ethidium bromide (EtBr) is commonly used as a non-radioactive marker for identifying and visualizing nucleic acid bands in electrophoresis and in other methods of nucleic acid separation. While in small doses it is useful, it must be handled with care and disposed of as a mutagen. ETHIDIUM BROMIDE: While not regulated as a "hazardous waste", the mutagenic properties of this substance may present a hazard if improperly disposed of down the drain or placed into the trash. Ethidium bromide is an intercalating agent, so it bind to DNA and will force replication errors, so it impossible to predict the symptoms that will results from this mutation but cancer can be one. inserts itself between the strands), deforming the DNA. 11th May, 2020. anything capable of binding DNA with high affinity is a possible mutagen. Ethidium bromide is a toxic chemical and a mutagen. EtBr is a potent mutagen (can cause genetic damage), and moderately toxic after an . It's not a mouse mutagen or rat mutagen either. Ethidium bromide is a sensitive, easy stain for DNA. Label as Ethidium Bromide (Mutagen) Waste-Sharps.

Ethidium bromide is thought to act as a mutagen because it bonds in double stranded DNA, thereby deforming the molecule.
