A selective indicator for the detection of Highly Reactive Oxygen Species, hROS.
A new novel probe, Aminophenyl fluorescein (APF), developed by Tetsuo Nagano et. al. (1), is a general selective indcator for the detection of highly Reactive Oxygen Species (hROS). The probe has little reactivity towards other ROS such as: singlet oxygen (O21), superoxide (O2-•), hydrogen peroxide (H2O2), nitric oxide (NO•), and alkyl peroxide (RO2•) (see table below)1. APF is a cell permeable indicator that can be used to detect Hydroxyl Radical (.OH), Peroxynitrite: (ONOO-) and hypochlorite (-OCl) production in cells.Several fluorescent probes such as 2",7"-dichlorodihydrofluorescein (DCFH) and di-hydrorhodamine123, have been developed to detect Reactive Oxygen Species (ROS). As Hempel and co-workers have indicated, DCFH and di-hydrorhodamine123 can react with various ROS and oxidizing species such as hydrogen peroxide, hypochlorite, superoxide, nitric oxide, ferrous ion, and others. These probes should be considered as detecting a broad range of ROS.
