In this report we present a new chemical probe, 3-HTC, that can reversibly and ratiometrically measure the thiol-disulfide equilibrium of biological systems. 3-HTC is composed of a coumarin that has a thiolate directly conjugated to its extended aromatic pi system while formation of a disulfide attenuates this conjugation. The fluorescence and absorption properties of 3-HTC are therefore very sensitive to the redox state of its thiol. 3-HTC reacts reversibly with thiols and disulfides enabling its use to measure dynamic GSH/GSSH ratios in vitro as well as to monitor the reversible redox status of whole cell lysates.
