Live/Dead Fix Lime

Live/Dead Fix Lime (Ex-Max 408 nm/Em-Max 504 nm)

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 Lime has an excitation peak at 408 nm and an emission peak at 504 nm.
