General description

Extinction coefficient(493 nm): 5900 M -1cm-1;(287 nm): 55,700 M -1cm-1;
Membrane impermeable DNA intercalator. Has red fluorescence at 488 nm. Useful for flow cytometry for staining apoptotic cells and nuclei. Can be used to differentiate between apoptotic and necrotic cell death while stains only necrotic cells. Can be used together with common green fluorescent probes labeled with fluorescein isothiocyanate (FITC).
Membrane impermeable DNA intercalator. Has red fluorescence at 488 nm. Useful for staining apoptotic cells and nuclei by flow cytometry. Can be used to differentiate between apoptotic and necrotic cell death. Can be used together with common green fluorescent probes labeled with fluorescein isothiocyanate.
