    Product Description

    Pentafluorobenzenesulfonyl fluorescein is a fluorescent probe that functions by a nonoxidative mechanism. It fluoresces upon perhydrolysis of the sulfonyl linkage, and is selective for hydrogen peroxide over hydroxyl radical, tert-butyl hydroperoxide, superoxide anion, singlet oxygen, and nitrates. Pentafluorobenzenesulfonyl fluorescein can be used as a probe for hydrogen peroxide in whole cell systems.1

    WARNING This product is not for human or veterinary use.
