What is Glutathione??

L-Glutathione Reduced (GSH, γ-L-Glutamyl-L-cysteinylglycine, CAS 70-18-8) is the most abundant intracellular antioxidant tripeptide. Molecular formula C₁₀H₁₇N₃O₆S, MW 307.32 g/mol. GSH is a critical substrate for glutathione peroxidase (GPx), glutathione S-transferase (GST), and glutaredoxin — neutralising reactive oxygen species, detoxifying xenobiotics, and maintaining thiol-redox homeostasis. In research settings, GSH is used to study oxidative stress, immune function, liver detoxification, and the γ-glutamyl cycle (GGT/GSS/GSR pathways).

Research Applications

Oxidative Stress Research

ROS scavenging, lipid peroxidation (MDA, 4-HNE), protein carbonylation quantification

Glutathione Peroxidase / GST

Enzyme activity assays, H₂O₂ and organic peroxide reduction, xenobiotic detoxification

Immune Function

Lymphocyte proliferation, NK cell activity, Th1/Th2 cytokine balance under GSH depletion/repletion

Liver Detoxification

Phase II conjugation, hepatoprotective models (acetaminophen, CCl₄), GSH depletion kinetics

Glutathione Cycling

GSH/GSSG ratio, glutathione reductase (GSR), GGT pathway, thiol-redox homeostasis

Frequently Asked Questions

How do I reconstitute Glutathione?
Add 1–2mL bacteriostatic water or sterile saline to the lyophilized glutathione vial. Dissolves readily to a clear solution. Glutathione can be sensitive to oxidation — use within 7–14 days of reconstitution and avoid exposure to air where possible.
How should Glutathione be stored?
Store lyophilized at −20°C, protected from light and moisture. Reconstituted: 2–8°C, use within 7–14 days. Glutathione (GSH) is susceptible to oxidation — it converts to GSSG over time in aqueous solution. Fresh-preparation is preferable.
What purity is Vesta Glutathione and how is it verified?
Vesta Glutathione (γ-glutamylcysteinylglycine) is ≥99% HPLC pure with MS confirmation on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
