What is glutathione?
Glutathione (GSH) is a tripeptide of γ-glutamyl-cysteine-glycine. It occurs endogenously in mammalian cells and is one of the most studied molecules in oxidative-stress research. Index Peptides supplies the reduced form, L-glutathione, produced for laboratory use.
Glutathione is classified as a research chemical in this context, and Index Peptides supplies it strictly for in-vitro laboratory research.
Glutathione in the research literature
Reduced glutathione appears across a large body of biochemistry literature concerned with redox state, oxidative stress models and analytical method development. The research context is broad and predominantly laboratory-based; Index Peptides takes no position on any application.
Form, handling and storage
Glutathione is supplied as a lyophilised (freeze-dried) powder in a sealed vial. Lyophilised material is best stored at -20°C, desiccated and protected from light; long-term stability data are batch-specific and recorded against the batch record.
Batch documentation at Index Peptides
Review the published certificate for the exact lot, including the laboratory, report date and analytical results actually reported. HPLC purity alone does not confirm LC-MS identity. Contact us before ordering if a required result is not published.
Frequently asked questions
Who is glutathione supplied to?
Index Peptides supplies glutathione exclusively to qualified researchers and licensed laboratories, for in-vitro research only. It is not for human or veterinary use.
What is the CAS number for glutathione?
70-18-8 for reduced L-glutathione (GSH), with a molecular weight of approximately 307.3 g/mol.
How is each batch verified?
Each published batch record shows the reversed-phase HPLC purity result and states when no LC-MS identity result has been published. Records are linked from the product page, and any batch can be checked by lot number on the verify page.
What is the shelf life of Glutathione?
As supplied (lyophilised powder in a sealed vial), Glutathione is stored at -20C, desiccated and protected from light. Long-term stability is documented per batch on the certificate of analysis; treat the batch record as the authoritative shelf-life reference for that lot.
What is the difference between the sizes?
The difference is the nominal peptide content per vial. Glutathione is supplied as 1500mg vials. Every format carries the same batch documentation and purity testing.
What does the certificate of analysis show?
Review the published certificate for the exact lot, including the laboratory, report date and analytical results actually reported. HPLC purity alone does not confirm LC-MS identity. Contact us before ordering if a required result is not published.
