Ethidium homodimer I

Ethidium homodimer is a red fluorescent dye. It cannot cross an intact plasma membrane, but can easily pass through a damaged plasma membrane. Ethidium homodimer is used to check membrane integrity. One molecule of EthD-1 will non-selectively bind four base pairs in dsDNA.


  • Ethidium homodimer I solution has been used to check membrane integrity in sperms
  • Stains ssDNA, dsDNA, RNA, oligonucleotides, and triplex DNA structures
  • Used to detect DNA in solution
