Glutathione (L-γ-Glutamyl-L-cysteinyl-glycine) is a naturally occurring tripeptide antioxidant found in virtually all mammalian cells. In its reduced form (GSH), it is the most abundant intracellular antioxidant and serves as the primary cellular defense against oxidative stress. Heartland Bio Labs supplies Glutathione (reduced form) as a high-purity lyophilized research compound for qualified laboratory applications.
Glutathione is among the most extensively studied molecules in cellular redox biology. Research has characterized its roles in reactive oxygen species (ROS) scavenging, xenobiotic detoxification, immune cell function, protein disulfide regulation, and mitochondrial protection. The GSH/GSSG ratio is a widely used biomarker in oxidative stress research. Glutathione is also studied in the context of detoxification pathway biology and its interactions with glutathione S-transferase enzymes.
This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.
Handling Information
Handle under standard laboratory conditions. Glutathione (reduced form) is susceptible to oxidation when exposed to air. Handle quickly, minimize exposure to oxygen, and store in tightly sealed containers. Use appropriate PPE. This compound is intended for qualified research use only.
Storage Requirements
- Long-term (lyophilized): Store at -20°C, protected from light and oxygen
- Short-term (in solution): Use immediately or store at -80°C; do not store reconstituted solution at 4°C for extended periods
- Keep in original sealed vial under inert gas conditions when possible
