Hoechst 34580 *20 mM solution in water*
The Hoechst stains are a family of fluorescent stains for labeling DNA in fluorescence microscopy. Because these fluorescent stains label DNA, they are also commonly used to visualize nuclei and mitochondria. Hoechst 34580 can be excited by violet laser at 405 nm, and emit blue/cyan fluorescence light around an emission maximum at ~440 nm. It is cell-permeable and provide an excellent tool for flow cytometers equiped with a 405 nm violet laser source.
