Ethidium Homodimer III was developed by Biotium as an alternative to Ethidium Homodimer I. It has absorption and emission spectra similar to those of Ethidium Homodimer I. However, the dye stains DNA 70% brighter than Ethidium Homodimer I. The dye is also a component of our Cell Viability/Cytotoxicity Assay Kit for detecting both live and dead cells in the same population (30002). See Figure 9.5 for spectra.
