NucSpot® Far-Red, 1000X in DMSO
NucSpot® Far-Red was designed to be an improved alternative to 7-AAD for selective detection of dead cells by flow cytometry.
NucSpot® Live Cell Nuclear Stains
NucSpot® Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stains nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have low toxicity for live cell imaging.
Propidium Iodide (PI)
Propidium iodide (PI) is a membrane-impermeant nucleic acid intercalator. The dye is commonly used to selectively stain dead cells in a cell population and also used as a counterstain in multicolor fluorescent imaging.
