About Glutathione as a reference compound
Glutathione is the reduced tripeptide antioxidant supplied as a high-purity reference standard for redox assays. Every PureLabs lot is produced under GMP-aligned synthesis controls, filled and sealed in a controlled environment, then assayed by an independent partner laboratory using reverse-phase HPLC with mass-spectrometric confirmation. Material is released only at or above the stated ≥99% threshold; anything below it is rejected rather than sold. The certificate of analysis carries the chromatogram and MS trace for the exact lot you receive and stays archived under reference PL-1273 for the life of the batch. Available in 1 kit configuration, each containing ten vials.
Handling and storage
- Store sealed Glutathione vials at −20 °C, protected from light.
- Reconstitute with bacteriostatic or sterile water added slowly down the vial wall; swirl, never shake.
- Hold reconstituted solution at 2–8 °C and use within roughly 21 days.
- Aliquot before freezing so the material never sees repeated freeze–thaw cycles.
Glutathione — frequently asked questions
Common laboratory questions about sourcing, purity, storage and shipping of Glutathione.
What sizes of Glutathione can I order?
Glutathione ships in 1 configuration: 1,500 mg/vial · 10 vials/kit. Prices start at $100 per kit.
What purity is PureLabs Glutathione?
Current stock assays at ≥99% by reverse-phase HPLC with mass-spectrometric confirmation from an independent laboratory. Lots below the threshold never reach the catalog.
Does Glutathione ship with a certificate of analysis?
Yes. A lot-specific certificate of analysis including the HPLC chromatogram and MS trace accompanies every order and remains retrievable under batch reference PL-1273.
How should Glutathione be stored?
Sealed lyophilized Glutathione is stable at −20 °C for at least 24 months. Once reconstituted, hold at 2–8 °C and use within about three weeks.
How quickly does Glutathione ship?
Orders confirmed before 15:00 UTC dispatch the same working day in insulated, tracked packaging, subject to the import rules of the destination country.
Is Glutathione sold for human use?
No. PureLabs supplies this material strictly as a reference compound for in-vitro and laboratory research. It is not a medicine and is not for human or veterinary consumption.
