Ethidium Homodimer, is a high affinity fluorescent nucleic acid stain. It binds to both DNA and RNA in a sequence-independent manner and with a >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.

Ethidium Homodimer-1 (EthD-1) is red solid, and with molecular weight is 857. Abbkine supplies below price/size for your choice: $218.4/1mg, $1638/10 mg.

The Ethidium Homodimer-1 (EthD-1) has below features:  λEx/λEm: 528/617 nm(with DNA), 493 nm(in H2O, no DNA).
