Invitrogen™ LIVE/DEAD™ Cell-Mediated Cytotoxicity Kit, for animal cells

The LIVE/DEAD™ Cell-Mediated Cytotoxicity Kit measures natural killer (NK) cell-mediated, lymphokine-activated killer (LAK) cell-mediated and T cell mediated cytotoxicity. Target cells are preincubated with the green-fluorescent membrane stain DiOC₁₈ and then mixed with effector cells in the presence of the red-fluorescent, membrane-impermeant dye, propidium iodide. Live and dead target cells retain the green-fluorescent membrane stain; target and effector cells with compromised membranes exhibit red-fluorescent nucleic acid staining; live effector cells are nonfluorescent.
