Total Glutathione (T-GSH)/Oxidized Glutathione (GSSG) Colorimetric Assay Kit

Glutathione is a tripeptide (γ-L-glutamyl-L-Cysteinyl glycine) and the most common intracellular thiol. In cells, glutathione exists in two different forms, reduced (GSH) and oxidized (GSSG). Under physiological conditions, more than 98% of intracellular glutathione is GSH, because GSSG is rapidly reduced to GSH by glutathione reductase. GSH-GSSG system is the most abundant oxidation-reduction system in eukaryotic cells. It plays an important role in cell homeostasis and participates in apoptosis-related signal transduction.
