Overview+

L-Glutathione is a tripeptide and one of the primary intracellular antioxidants. It is studied for its role in redox balance, detoxification pathways, and cellular protection against oxidative stress, functioning as the cell's main low-molecular-weight thiol buffer.

History+

Characterized in the early 20th century and studied extensively by Meister and others, glutathione is among the most abundant low-molecular-weight thiols in living cells and has been a long-standing subject of redox biology. Decades of work established its central place in antioxidant defense and detoxification, making it a reference molecule for thiol chemistry.

Research findings+

L-Glutathione has been studied in cellular and systemic models for reactive-oxygen-species buffering, glutathione-S-transferase detoxification, and thiol-redox signaling. Its thiol group is what ties together its antioxidant, detoxification, and signaling roles, since the same chemistry that neutralizes reactive species also drives conjugation and redox regulation. As the dominant intracellular thiol, it functions as a baseline reference for studies of oxidative stress and cellular protection.

Key areas of research
  • →Antioxidant: ROS scavenging, redox buffering
  • →Detoxification: Conjugation and clearance pathways
  • →Systemic: Cellular protection, redox homeostasis

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
