Application

Fluorescent reagent for the detection of highly reactive oxygen species (hROS). Fluorescence intensity increases after the immediate reaction with hROS such as hydroxyl radical and peroxynitrite. Since HPF does not react with nitric oxide, superoxide and hydrogen peroxide, it can differentially detect peroxynitrite. HPF is resistant to light-induced autoxidation.
