About Live-or-Dye 665/685

Biotium’s Live-or-Dye dyes are amine-reactive and used for live/dead cell discrimination in conjunction with flow cytometry or microscopy. These stains pass through the permeable cell membrane of dead cells to stain intracellular amine groups, while the stains cannot pass through the intact membranes of live cells. Additionally, these dyes are very stable and can withstand fixation, permeabilization, and will not transfer between cells. This dye line has many color options, some of which were designed with spectral flow cytometry in mind. Check out all members of this dye line in FluoroFinder’s Dye Directory or on our Spectra Viewer.
