Glutathione in Research
Glutathione (GSH) is the master intracellular antioxidant — a tripeptide of glutamate, cysteine, and glycine present at millimolar concentrations in most cells. Research spans redox regulation, free-radical scavenging, and hepatic phase II detoxification, where GSH conjugation is the workhorse mechanism for xenobiotic clearance in model systems.
Supplied as 1500mg of lyophilized ≥99% material with independent batch documentation — the largest single-vial quantity in our catalog, sized for cell-culture and biochemical assay work.
Research Overview
- Studied as a primary intracellular redox regulator and free-radical scavenger
- Investigated for hepatic phase II detoxification and xenobiotic conjugation pathways
- Research into mitochondrial glutathione pools and oxidative stress resilience
- Explored for dermatologic pigmentation and tyrosinase pathway modulation in vitro
- Preclinical studies on immune cell redox balance and cytokine signaling
Quality & Testing
Every Glutathione batch is verified by independent third-party HPLC and mass-spectrometry testing, with a batch-specific certificate of analysis available on the COA page.
Laboratory Handling & Storage
Lyophilized peptides are supplied as a freeze-dried powder and are most stable stored cold (2–8°C), protected from light and moisture, in the original sealed vial. Under these conditions the research literature generally reports multi-year integrity for dry peptide material.
Once reconstituted in a laboratory setting, solutions are typically stored refrigerated and used within the window appropriate to the diluent and compound; repeated freeze–thaw cycles are avoided because they can promote aggregation. See our research overview on reconstitution and lyophilization for the underlying formulation science.
The cysteine thiol oxidizes readily in solution; laboratory protocols prepare GSH solutions fresh and minimize air exposure to preserve the reduced form.
Frequently Asked Questions
What is glutathione?
Glutathione is the endogenous tripeptide γ-Glu-Cys-Gly, the primary intracellular redox buffer, studied across antioxidant, detoxification, and redox-signaling research.
Why does the reduced form matter in the laboratory?
Biological activity in redox assays belongs to reduced GSH; the thiol oxidizes to GSSG on air exposure, so solutions are prepared fresh and handled to minimize oxidation.
Is glutathione for human use?
No. This material is a laboratory reagent for research use only — not a supplement and not for human consumption.
