    Assay Principle: The DetectX® Glutathione (GSH) Colorimetric Cuvette Detection Kit is designed to quantitatively measure glutathione (GSH), and oxidized glutathione (GSSG) present in a variety of samples. No separation or washing is required. Please read the complete kit insert before performing this assay.

    Background: Glutathione (L-γ-glutamyl-L-cysteinylglycine; GSH) is the highest concentration non-protein thiol in mammalian cells and is present in concentrations of 0.5 – 10 mM. GSH is a tripeptide molecule. It contains a peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species. Glutathione reduces disulfide bonds formed within cytoplasmic proteins to cysteines by serving as an electron donor. Glutathione is converted to its oxidized form, glutathione disulfide (GSSG). It’s reduced form is most common since glutathione reductase is constitutive and inducible upon oxidative stress. The ratio of reduced glutathione to oxidized glutathione within cells is often used as a measure of cellular toxicity.
