Ethidium bromide (EB) A trypanocidal agent and possible antiviral agent that is widely used in experimental cell biology and biochemistry. Ethidium has several experimentally useful properties including binding to nucleic acids, noncompetitive inhibition of nicotinic acetylcholine receptors, and fluorescence among others. It is most commonly used as the bromide. Ethidium bromide has a λEx of 300-360 nm and a λEm of 590 nm.

Ethidium monoazide bromide, a fluorescent dye that intercalates with DNA, selectively penetrates bacteria possessing compromised membranes. Upon photoactivation, it forms covalent bonds with DNA, enabling it to exclusively stain dead cells [1].

Acridine ethidium heterodimer is a fluorescent indicator.

EthD-1 is a cell-impermeant viability indicator. It acts as a high-affinity nucleic acid stain.

Dihydroethidium (PD-MY 003) is a superoxide indicator.

The strong EB detoxification agent is specially designed to remove the contaminated product of Ethidium bromide (EB).It can effectively destroy the structure of EB, remove the carcinogenicity of EB, so as to achieve the purpose of cleaning EB pollution.It
