Product Description
Thiazole Red Homodimer (TRhD), also known as TOTO®-3, is a cell-impermeant, high-affinity nucleic acid stain based upon a symmetric cyanine dye dimer. The dye is essentially non-fluorescent in the absence of nucleic acids, but exhibits bright far-red fluorescence when bound to nucleic acids. TRhD is also used as a nuclear counterstain and dead cell indicator.
- Dimeric nucleic acid stain
- Cell-impermeant
- λEx/λEm (with DNA) = 642/661 nm
- Supplied at 1 mM in DMSO
- C53H62I4N6S2
- MW: 1355
