Product Description

7-AAD Cell Staining Solution is supplied in an aqueous buffered solution containing less than 0.09% sodium azide. It can be used to stain apoptotic cells.


7-Aminoactinomycin D (7-AAD) is a fluorescent DNA dye that binds poly(dG-dC) regions with an excitation maxima at 543 nm when bound to DNA (1). 7-AAD can be used as dead cell discriminating dye due to its exclusion from live cells with intact membranes (2).
