Additionally, DAPI may be used to analyze DNA content in fixed cells, or as a nuclear counterstain in imaging or flow cytometry. Wavelength. DAPI is cell permeable and is readily used for detecting both live, dead and fixed cells. Emission. The large product range includes longpass filter cubes for observation of single-stained samples and bandpass filter cubes suitable for detecting specific wavelengths from multiple-stained samples and unmixing. The DAPI-RNA complex is much less well excited by UV light than is the DNA complex, but much better excited at 405 nm than in the UV, and the emission of the DAPI-RNA complex is substantially higher at longer wavelengths. This discussion centers around filter and cube choice, function, and nomenclature. The increase in fluorescence is believed to be due to displacement of water molecules from the minor groove and DAPI. 616 nm.
