Product Description
Thiazole Red, also known as TO-PRO®-3, is a cell-impermeant, high-affinity carbocyanine monomeric nucleic acid stain that is essentially non-fluorescent in the absence of nucleic acids but exhibits excitation/emission maxima ~642/657 nm when bound to nucleic acids. Thiazole Red is also used as a nuclear counterstain and dead cell indicator.

- Cell-impermeant
- λEx/λEm (with DNA) = 642/657 nm
