Green CMFDA (Highly Pure) by Molecular Depot is a cell-permeable fluorescent probe, 5-chloromethylfluorescein diacetate (CMFDA), that enters living cells freely. Intracellular esterases remove the acetate groups and the chloromethyl group reacts with thiols, so the dye becomes trapped and fixed in place. It is used for long-term cell tracking, in cell viability and migration assays and as a thiol-reactive cell tracer. Each unit contains 1 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
