SELECTFX NUCLEAR LABELING KIT 1 KIT，S33025，Invitrogen

The SelectFX® Nuclear Labeling Kit provides four spectrally distinct fluorescent dyes for staining nuclei in fixed-cell preparations: blue-fluorescent DAPI, green-fluorescent SYTOX® Green stain, red-fluorescent 7-aminoactinomycin D (7-AAD), and far red-fluorescent TO-PRO®-3 dye. These dyes are ideal for use as counterstains in multicolor applications; simply select the stain that contrasts spectrally with other fluorescent probes applied to the sample. When used according to the protocol provided, the dyes in the SelectFX® Nuclear Labeling Kit provide highly selective nuclear staining with little or no cytoplasmic labeling.
