产品描述：

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

The dye is excluded by live cells and early apoptotic cells, but stains necrotic and late apoptotic cells with compromised

membrane integrity. 7-AAD/DNA complexes can be excited at 488 nm with an argon-ion laser, and has a large Stokes shift with an emission

maxima of 647 nm (1-3). 7-AAD intercalates selectively at GC-rich regions of DNA, which makes the dye useful for chromosome

banding studies (4). 7-AAD can be used in multicolor fluorescence microscopy and flow cytometry.
