It binds to both DNA and RNA in a sequence-independent manner and with a &gt;30-fold fluorescence enhancement. The DNA binding of each Ethidium Homodimer covers four base pairs and is believed to occur by intercalation. Because the dye is highly positively charged, it can not cross cell membranes to stain living cells. However, it is very useful to detect nucleic acids in solution, or cells with disintegrated cell membranes. Biotium offers a high purity grade Ethidium Homodimer that is not available from anywhere else. Ethidium Homodimer from other suppliers often contains a high amount (as much as 20%) of inorganic salt that lowers the weight percent purity.\u00a0 <\/p>\n<ul>\u00a0 <\/p>\n<li>&amp;lamba;<sub>Ex<\/sub>\/&amp;lamba;<sub>Em<\/sub> (with DNA) = 528\/617 nm<\/li>\n<p>\u00a0 <\/p>\n<li>&amp;lamba;<sub>Ex<\/sub>\/&amp;lamba;<sub>Em<\/sub> (in H<sub>2<\/sub>O, no DNA) = 493 nm<\/li>\n<p>\u00a0 <\/p>\n<li>Red solid soluble in DMSO or MeOH<\/li>\n<p>\u00a0 <\/p>\n<li>Store at 4\u00b0C and protect from light<\/li>\n<p>\u00a0 <\/p>\n<li>C<sub>46<\/sub>H<sub>50<\/sub>Cl<sub>4<\/sub>N<sub>8<\/sub><\/li>\n<p>\u00a0 <\/p>\n<li>Mwt: 857<\/li>\n<p>\u00a0 <\/p>\n<li>[61926-22-5]<\/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>Ethidium Homodimer, first developed by Dr. Le Pecq and his colleagues, is a high affinity fluorescent nucleic acid stain.
