What is L-Glutathione?
L-Glutathione is the tripeptide gamma-glutamyl-cysteinyl-glycine, the principal intracellular thiol antioxidant and a substrate in phase II conjugation. It is supplied here in the reduced form, which is the one assays generally specify. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.
What is L-Glutathione studied for?
- Redox-state and oxidative-stress assays
- Glutathione peroxidase and reductase studies
- Phase II conjugation research
- Thiol quantification method development
All applications above are in-vitro or preclinical research contexts. L-Glutathione is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot LGL-2609-X show?
Every lot of L-Glutathione is tested by an independent US laboratory before it is listed. The report for lot LGL-2609-X is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot LGL-2609-X result |
|---|---|---|
| Identity | LC-MS | Matches the calculated mass for the sequence |
| Purity | HPLC-UV, 220 nm | 99.0% |
| Net peptide content | Amino acid analysis | Stated per vial on the certificate |
| Endotoxin | LAL, chromogenic | < 0.5 EU/mg |
| Sterility | USP <71> | Pass |
How is L-Glutathione handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within the 28-day window on the certificate. The reconstitution guide covers volumes and syringe units and the concentration table gives the numbers for this vial.
Frequently asked questions
Is this reduced or oxidised glutathione?
Reduced (GSH). The oxidised dimer (GSSG) is a different compound and most protocols are explicit about which they need.
How stable is it in solution?
Reduced glutathione oxidises readily in air. Prepare fresh where the redox state matters and record the interval in your methods.
Is L-Glutathione for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
