About Live-or-Dye 665/685
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™ 665/685 has an excitation peak at 665 nm and an emission peak at 685 nm.
