7-AAD (7-aminoactinomycin D) is a fluorescent DNA binding dye that is membrane impermeant and therefore generally excluded from viable cells.

Ethidium Homodimer III (EthD-III)
A red fluorescent dead cell stain for bacteria and mammalian cells that is brighter than Ethidium Homodimer I.
NucSpot® Far-Red, 1000X in DMSO
An improved alternative to 7-AAD showing less bleed-through fluorescence in the PE-Texas Red® channel. Ideal for selective detection of dead cells by flow cytometry.
NucSpot® Live Cell Nuclear Stains
No-wash, fluorescent DNA nuclear stains dyes with low toxicity for long-term live cell imaging or fixed cell staining. Choose green or far-red fluorescence.
Propidium Iodide (PI)
A membrane-impermeant nucleic acid intercalator. The dye is commonly used to selectively stain dead cells in a mixed live-dead population and also used as a counterstain in multicolor fluorescent assays.
