Glutathione Reductase Activity Colorimetric Assay kit
Highly Sensitive Assay, HTS
Glutathione Reductase (GR, EC 22.214.171.124) catalyzes the NADPH-dependent reduction of oxidized glutathione
(GSSG) to reduced glutathione (GSH), which plays an important role in the GSH redox cycle that maintains
adequate levels of reduced GSH. A high GSH/GSSG ratio is essential for protection against oxidative stress.
HansaBioMed’s Glutathione Reductase Assay Kit is a highly sensitive, simple, direct and HTS-
readycolorimetric assay for measuring GR activity in biological samples. In the assay, GR reduces GSSG to
GSH, which reacts with 5, 5′-Dithiobis (2-nitrobenzoic acid) (DTNB) to generate TNB2- (yellow color, λmax =
405 nm). The assay can detect 0.1 – 40 mU/ml GR in various samples.
• Simple procedure; takes ~ 30-40 minutes
• Fast and convenient
