Tonbo's Ghost Dyes™ & Cell Viability Reagents allow for clear live vs. dead cell discrimination for more precise flow cytometry analysis, and are especially useful for intracellular staining protocols.

Ghost Dyes™ bind irreversibly to amine groups and are resistant to subsequent washing, fixation and permeabilization. Dead cells with compromised membranes allow Ghost Dyes™ to permeate and bind amine groups of intracellular proteins resulting in fluorescence much brighter than live cells which are impermeant to Ghost Dyes™
