OUTLINECMFDA (5-chloromethylfluorescein diacetate) is a lipophilic tracer that has an enormous advantage over ordinary tracers (e.g. FITC) because it can be introduced into live (!) cells. Once inside the cell this dye undergo some covalent changes restricting from its passgae to extracellular milieu.
