About Live-or-Dye 787/808

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™ 787/808 has an excitation peak at 783 nm and an emission peak at 807 nm. In flow cytometry, this probe requires either a 785 or 808 nm laser.
