The cell-impermeant viability indicator, Nucleic acid staining probe which has higher affinity for nucleic acid than ethidium bromide. It is weakly fluorescent until bound to DNA and emits red fluorescence (excitation/emission maxima ~535/624). The DNA affinity of EthD-2 is about twice that of EthD-1 (7000). EthD-2 is also about twice as fluorescent bound to dsDNA than to RNA. The spectra and other properties of the EthD-1 and EthD-2 dimers are almost identical
