Product Description: 3-HTC is a chemical fluorescent probe. 3-HTC reacts reversibly with thiols and disulfides, and can be used to measure dynamic GSH/GSSH ratios in vitro as well as to monitor the reversible redox status of whole cell lysates (λmax: 448 nm in its reduced thiolate form, and a λmax 370-410 nm for the oxidized mixed disulfide)[1].
Formula: C16H9NO2S2
