Lyophilized Glutathione Powder

Key Features

• ≥ 98 % Purity (HPLC‑Verified): Ensures minimal impurities for reproducible antioxidant and enzymatic studies PubMedPMC.

• Lyophilized Format: Freeze‑drying preserves chemical integrity and guarantees a shelf life of ≥ 2 years when stored desiccated at −20 °C.

• Master Antioxidant: Scavenges ROS, lipid hydroperoxides, and heavy metals, protecting cellular components from oxidative damage PubMedPMC.

• Enzyme Cofactor: Required by glutathione peroxidases (GPx‑1/GPx‑4) to detoxify peroxides and by glutathione S‑transferases for xenobiotic conjugation PMCPMC.

• Dual Redox Function: Exists as reduced (GSH) and recycled oxidized (GSSG) forms, maintaining intracellular redox homeostasis PMCPubMed.

• Low Endotoxin: Validated for sensitive in vitro assays, minimizing confounding immune activation in cell culture.

Specifications

Applications

• Cell Culture Supplement: Prevents oxidative‑stress artifacts in neuronal, immune, and stem cell models by replenishing intracellular GSH pools.

• Redox & Aging Research: Probes sirtuin and PARP pathways, models senescence, and evaluates antioxidant interventions in vitro and in vivo PMCPMC.

• Enzymatic & ELISA Standards: Serves as a quantitative substrate or cofactor in kinetic assays for GPx, GST, and glyoxalase enzymes PMCMP.

• Detoxification Studies: Supports phase II conjugation assays for drug‑metabolism and xenobiotic clearance research PMC.

• Synthetic Biology & Biochemical Engineering: Integrates into microfluidic reactors and metabolic‑flux analyses requiring tight redox control PMC.
