ethidium

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.

Acridine ethidium heterodimer is a fluorescent indicator.

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].

Dihydroethidium (PD-MY 003) is a peroxide indicator with blue fluorescence in the cytoplasm (λex=518 nm, λem=616 nm), which disappears when oxidized and is cell permeable.

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

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
