Hydroxyphenyl Fluorescein

Hydroxyphenyl Fluorescein (HPF) is a cell-permeable, low-background fluorescent probe designed for selective detection of highly reactive oxygen species (hROS) . It is widely applied in both in vitro and in vivo research, including studies of oxidative stress in neurodegeneration, aging, and inflammatory models, utilizing techniques like flow cytometry and fluorescence microscopy (Ex/Em = 490/515 nm) .
