产品概述
Glutathione Reductase Assay Kit (ab83461) is a highly sensitive, simple, direct and HTS-ready colorimetric 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.
Since Glutathione Reductase has significantly higher concentrations in cells (mM range) compared to Thioredoxin Reductase (µM range), we predict that ab83461 will detect mostly GR activity in samples.

说明
This product is manufactured by BioVision, an Abcam company and was previously called K761 Glutathione Reductase Activity Colorimetric Assay Kit. K761-200 is the same size as the 200 test size of ab83461.
Glutathione Reductase (GR, EC 1.8.1.7) 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.

ICAC decreased the ROS level induced by EV71 infection via modulating the antioxidant enzymes involved in GSH metabolism. Infected (100 TCID50 EV71) Vero cells were treated with medium or 100 µM ICAC for 12 h. Uninfected cells were used as the control group. The antioxidant enzymes activities of the Vero cells were detected (n = 3). All results were expressed as the means ± SEs. Asterisks indicate that the data significantly differ from the EV71 group at the P < 0.05 level according to one-way analysis of variance.
