Ethidium homodimer I (EthD-I) is a membrane-impermeable, high-affinity, nucleic acid stain. Selectively labels dead cells with compromised plasma membranes. Compatible with flow cytometry, fluorescence microscopy, and plate reader assays.
This compound is light sensitive; exposure to light may affect compound performance. We therefore recommend storing the solid material and any solutions in the dark and protecting from light.
