Reported use in research
Glutathione (GSH) is investigated as the principal low-molecular-weight thiol antioxidant and intracellular redox buffer of aerobic cells. In preclinical models it is studied for its capacity to scavenge reactive oxygen species and to maintain the reduced thiol status of proteins and enzymes. Research examines its role as a nucleophilic co-substrate for glutathione S-transferases in the conjugation and detoxification of electrophilic compounds. It is also investigated as an electron donor for glutathione peroxidases during the neutralization of peroxides. Additional studies explore the GSH/GSSG ratio as an index of cellular redox homeostasis and oxidative-stress balance in laboratory and animal research models.
Reported findings
Research reports that glutathione is among the most abundant intracellular thiols and that depletion of the cellular GSH pool is associated with increased markers of oxidative stress in laboratory models. In animal research models, alterations in the GSH/GSSG redox ratio have been observed in tissues subjected to oxidative challenge. Preclinical studies report interactions between glutathione and glutathione-dependent enzyme systems during xenobiotic conjugation. Investigations also describe a role for glutathione in maintaining the redox environment required for protein and enzyme function. These findings are observational and pertain strictly to controlled research settings.
Handling & safety
The full safety and toxicological profile of this research compound has not been completely characterized. It should be handled only by qualified personnel using appropriate laboratory protocols and personal protective equipment. Reconstituted material should be prepared under aseptic conditions and kept away from oxidizing agents, which can convert reduced glutathione to its disulfide form. This product is supplied for laboratory research use only and is not for human or veterinary use.
Reconstitution
Recommended ratio
- 10 mL of bacteriostatic water per 1500 mg vial
- Equivalent to 150 mg/mL (i.e. 15 mg per 10 units on a 100 U insulin syringe)
- Remove the plastic flip-off lid from the vial.
- Disinfect the rubber stoppers with alcohol wipes.
- Inject the diluent slowly down the inner wall of the vial to avoid foaming.
- Gently swirl the vial (never shake). Let it dissolve for about 10 minutes.
Storage
Unopened / before reconstitution
- Store at a stable temperature.
- Stable for 24 months.
- For long-term storage (2+ years), store at -20 °C.
Reconstituted solution
- Must be kept refrigerated.
- Avoid exposure to light and excessive heat.
