Overview
For quantitative determination of glutathione reductase activity. The assay uses OD412nm for signal readout. Compatible sample input includes Plasma, serum, tissue and culture media etc. Typical stated assay timing is 30 min.
Key elements and design rationale
- Readout format: OD412nm supports plate-based signal acquisition and consistent comparison across matched samples.
- Sample compatibility: The stated sample scope includes Plasma, serum, tissue and culture media etc, which is useful when aligning matrix type with calibration and control design.
- Analytical range context: The supplied specifications include a stated detection limit of 0.4 U/L for interpreting low-signal samples.
- Feature emphasis: Fast and sensitive. Linear detection range (20 µL sample): 0.4 to 50 U/L for 20 min reaction. Detection Limit of 0.4 U/L.
Additional feature notes highlight Convenient and high-throughput. Homogeneous “mix-incubate-measure” type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day. Available format information for this listing includes 100 Tests.
Biological background
This product is centered on measurement of glutathione reductase within the matrices described for the assay. In practice, datasets from this type of format are typically interpreted by comparing relative signal, activity, or abundance across matched control and experimental groups rather than relying on a single value in isolation. Careful alignment of sample matrix, incubation window, and calibration strategy is important when comparing results across plates, operators, or study days.
More details
GLUTATHIONE REDUCTASE (GR) reduces oxidized glutathione (GSSG) to the reduced sulfhydryl form GSH which is an important cellular antioxidant. A high GSH/GSSG ratio is important for protection against oxidative stress. Thus, measurement of GR activity is used as indicator for oxidative stress. BioAssay Systems’ non-radioactive, colorimetric GR assay is designed to accurately measure GR activity in biological samples with a method that utilizes Ellman’s method in which DTNB reacts with the GSH generated from the reduction of GSSG by the GR in a sample to form a yellow product (TNB 2- ). The rate of change in the optical density, measured at 412 nm, is directly proportional to GR activity in the sampl

Research relevance and current trends
- Plate-based quantification and side-by-side group comparison remain central use cases for this assay format.
- The product notes emphasize multi-sample throughput, making it relevant for screening-oriented and larger batch comparison studies.
- Short assay timing and plate compatibility support time-course or repeated-measure collection plans when handling is kept consistent.
Common research applications
- Quantify glutathione reductase in plasma, serum, tissue and culture media by OD412 nm readout.
- Compare treatment or phenotype groups using matched plasma, serum, tissue and culture media handling.
- Monitor time-course or pre/post changes in plasma, serum, tissue and culture media across study conditions.
Interpretation is usually strongest when signal changes are assessed alongside matrix-matched controls, replicate agreement, and the assay's stated analytical window.
Notes for experimental interpretation
- Matrix composition, background signal, and sample handling can influence apparent response; compare like-with-like whenever possible.
- Use appropriate blanks, controls, and replicate wells to distinguish biological differences from plate, reagent, or handling variability.
