NucSpot 470 is a cell membrane-impermeant green fluorescent DNA stain. It is virtually non-fluorescent in the absence of DNA, but fluoresces bright green upon DNA binding. While other green nucleic acid stains like TOTO, TO-PRO, or SYTOX dyes stain both the nucleus and cytoplasm, NucSpot 470 specifically stains the nucleus of fixed and permeabilized cells. It also can be used to selectively stain dead cells in living cultures. NucSpot 470 has an excitation/emission of 460/546 nm and can be imaged using standard settings for FITC. Properties: Ex/Em= 460/546 nm (with DNA); Store at 4C and protect from light.
