Description

Introduction

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 (2) 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 (2).

Key Benefits

  • Quenched Cell permeable dye.
  • One Step, No wash Homogenous assay.
  • Adaptable to High throughput assay platforms.
  • Can monitor multiple time points to follow real time kinetics.
  • Non-destructive cell based assay allows monitoring of additional parameters.
  • Applications – Fluorescent plate reader / Flow Cytometery / Fluorescent Microscopy.
