Description
The Glutathione Colorimetric Detection Kit from Arbor Assays quantifies free and oxidized glutathione (GSH and GSSG) in whole blood, serum, plasma, urine, cells, and tissues. Using a colorimetric substrate, the assay detects GSH through a direct absorbance read at 405 nm, without the need for separation steps. Sensitivity reaches 0.634 µM, and the detection range spans 0.781–25 µM for total GSH. The assay completes in just 20 minutes, offering a practical tool for monitoring oxidative stress, redox balance, and cellular health. Ideal for both endpoint and kinetic measurements across research fields such as metabolism, toxicology, and aging
