Research Background
Glutathione (GSH) is the principal intracellular non-protein thiol of eukaryotic cells and one of the most widely used laboratory reagents in redox biology. It serves as a cofactor for glutathione peroxidase and glutathione-S-transferase reactions, as a standard for analytical method development, and as a probe in oxidative-stress, conjugation and detoxification research. Supplied as the reduced (GSH) form.
Proposed Mechanisms
Research Focus Areas
Oxidative-stress and antioxidant-capacity assays
Reference standard for thiol quantification
Phase II conjugation pathway studies

FAQ
What form of glutathione do you supply?
The reduced form (GSH), CAS 70-18-8, molecular weight ~307.3 Da, as a white to off-white powder in 10-vial kits.
What purity is guaranteed?
≥99% by HPLC. The batch COA reports the analytical purity result and identity confirmation.
Why is glutathione in the cosmetic & skin category?
Because redox and thiol research is commonly carried out in dermal cell-culture systems. Note that this listing is a research reagent: it is not a cosmetic ingredient for human application, and no cosmetic or clinical claim is made.
How should glutathione solutions be handled?
Prepare solutions fresh where possible; GSH oxidises in solution over time. Store the powder sealed and desiccated at 2–8°C, protected from light and oxygen exposure.
