DAPI is a fluorescent DNA stain for use on fixed cells for applications such as imaging, mitochondrial DNA detection, or nuclear quantitation. This dye, often used as a counterstain in immunofluorescence, binds strongly to AT rich runs of nucleic acid, causing its fluorescent emission to increase. Ex 358 nm; Em 461 nm (dsDNA), Em 500 (RNA).
