DAPI
DAPI (4',6-Diamidino-2-Phenylindole, dihydrochloride) is a popular blue DNA dye that is used as a nuclear counterstain in fluorescence microscopy, chromosome staining and flow cytometry. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement, with higher affinity for A-T rich regions. Also see DAPI dilactate, a more water soluble form of the dye. </p> <ul> </p> <li>Classic blue nuclear counterstain for fixed cells</li> </p> <li>Can be used at higher concentrations to stain live cells</li> </p> <li> lamba;<sub>Ex</sub>/ lamba;<sub>Em</sub> = 358/461 nm (with DNA)</li> </p> <li>Off-white solid soluble in H<sub>2</sub>O</li> </p> <li>Store at 4°C and protect from light, especially in solution</li> </p> <li>C<sub>16</sub>H<sub>17</sub>Cl<sub>2</sub>N<sub>5</sub></li> </p> <li>MW = 350.25</li> </p> <li>[28718-90-3]</li> </p> </ul>
