Live-or-Dye™ Fixable Viability Staining Kits allow discrimination between live and dead cells by flow cytometry or microscopy. Live/dead stains are useful probes to include when analyzing cell surface protein expression by flow cytometry, because they allow intracellular fluorescence signal from dead cells with permeable plasma membranes to be excluded from analysis. Single Color Kit Components • Live-or-Dye™ fixable dead cell dye • Anhydrous DMSO Sampler Kit Components • 5 different Live-or-Dye™ fixable dead cell dyes • Anhydrous DMSO
