| PEP-GSSG001 | Core in vivo redox marker, substrate of glutathione reductase, indicator of cellular oxidative stress level | Oxidized glutathione is the oxidation product of reduced glutathione (GSH), and together they constitute the most important redox buffer pair in cells. GSSG serves as a specific substrate for glutathione reductase, used in enzyme activity assays and inhibitor screening. Its intracellular concentration and the GSH/GSSG ratio are gold standard indicators for evaluating oxidative stress, with elevation indicating cellular oxidative damage. Exogenous GSSG can induce cellular oxidative stress models to study the effects of oxidative damage on apoptosis, proliferation and protein folding. It is also widely used in mechanism research of liver injury, neurodegenerative diseases, aging and tumor drug resistance. | Oxidative stress research,Antioxidant mechanism study,Glutathione pathway study,Apoptosis research,Liver injury study,Aging and degenerative disease research | Glutathione redox pair; Glutathione reductase catalytic pathway; Cellular oxidative stress and oxidative damage pathway |
