The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement, with higher affinity for A-T rich regions. DAPI dilactate is essentially the same as DAPI dihydrochloride, but with a different counterion. The dilactate salt form of the dye is more water soluble than the dihydrochloride salt, and therefore DAPI dilactate is a better choice for preparing stock solutions in water.\u00a0 \u00a0 <\/p>\n<ul>\u00a0 <\/p>\n<li>Classic blue nuclear counterstain for fixed cells<\/li>\n<p>\u00a0 <\/p>\n<li>Can be used at higher concentrations to stain live cells<\/li>\n<p>\u00a0 <\/p>\n<li>&amp;lamba;<sub>Ex<\/sub>\/&amp;lamba;<sub>Em<\/sub>(DNA) = 358\/461 nm<\/li>\n<p>\u00a0 <\/p>\n<li>Yellow solid soluble in water<\/li>\n<p>\u00a0 <\/p>\n<li>Store at 4\u00b0C and protect from light, especially in solution<\/li>\n<p>\u00a0 <\/p>\n<li>C<sub>22<\/sub>H<sub>27<\/sub>N<sub>5<\/sub>O<sub>6<\/sub><\/li>\n<p>\u00a0 <\/p>\n<li>MW: 457.49<\/li>\n<p>\u00a0 <\/ul>\n<h3>Handling<\/h3>\n<p>Store with desiccant; Protect from light<\/p>\n<div style=\"margin:18px 0 4px;padding:11px 14px;background:#fdf4f4;border:1px solid #e6bdbd;border-left:3px solid #c41e3a;border-radius:4px;font-size:13px;line-height:1.55;color:#3a3a3a\"><strong style=\"color:#8a1524\">For Research Use Only (RUO).<\/strong> This product is sold strictly for laboratory research use only. <strong>Not for human or veterinary consumption, therapeutic, or diagnostic use.<\/strong> Any pharmacological, therapeutic, cosmetic, or biological effects described above are provided as research context only and do not represent intended or approved uses of this product.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>DAPI is a popular blue DNA dye that is used as\u00a0a nuclear counterstain in fluorescence microscopy, chromosome\u00a0staining and flow cytometry.
