Abstract

Understanding the role of oxidative stress in disease requires real time monitoring of redox status within a cell. We report a FRET-based, ratiometric redox probe which can be applied to monitor cellular oxidative capacity using three different modalities – confocal microscopy, fluorescence lifetime imaging and flow cytometry.
