Live/Dead Fix Red

The Live/Dead Fixable Viability probes from Thermo Fisher 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/Dead Fixable Red has an excitation peak at 593 nm and an emission peak at 610 nm. see less The Live/Dead Fixable Viability probes from Thermo Fisher are amine-reactive and used for live/dead cell discrimination in flow cytometry.
