5(6)-CFDA SE Fluorescent pH Indicator by Molecular Depot is a reactive pH indicator (5(6)-CFDA SE) for the acidic pH range. Inside cells, esterases remove the acetates and the succinimidyl ester binds to amines, trapping the fluorescent dye. It is used to measure intracellular pH and, as CFSE after loading, to track cell division. Each unit contains 5 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
