About Live-or-Dye 640/662


Biotium's Live-or-Dye™ dyes are amine-reactive and used for live/dead cell discrimination in flow cytometry. These probes pass through the permeable cell membrane of dead cells to stain intracellular amine groups. However, the probe 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. Live-or-Dye™ 640/662 has an excitation peak at 640 nm and an emission peak at 662 nm.
