About Live-or-Dye 405/452

---

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™ 405/452 has an excitation peak at 405 nm and an emission peak at 452 nm.
