Description

  • About Glutathione (GSH / γ-L-Glutamyl-L-cysteinylglycine)

    AICAR — also known as Acadesine (CAS 2627-69-2) — is a cell-permeable nucleotide precursor and one of the most widely used pharmacological tools for studying AMP-activated protein kinase (AMPK) signaling in vitro and in preclinical models. It is supplied as a laboratory-grade lyophilized powder intended strictly for analytical and non-clinical research applications.

    Unlike exercise or caloric restriction, which activate AMPK by shifting the AMP:ATP ratio, AICAR is phosphorylated intracellularly to ZMP — an AMP mimetic that activates AMPK allosterically without depleting ATP. This makes it a uniquely clean pharmacological tool for isolating AMPK-dependent effects in cellular and preclinical models.

    COMMON RESEARCH APPLICATIONS

    Cellular Redox State & GSH/GSSG Ratio Assays
    Reference standard for GSH quantification using luminescent (Promega GSH-Glo), colorimetric (DTNB/Ellman s), or HPLC-based GSH/GSSG assays. Used to calibrate redox state measurements in oxidative stress models (H₂O₂, tBHP, BSO-induced depletion).

    Nrf2/Keap1 Pathway Research
    GSH depletion (BSO co-treatment) activates Nrf2/Keap1 antioxidant response. Used alongside buthionine sulfoximine (BSO) and Nrf2 activators (sulforaphane, CDDO-Me) to study antioxidant response element (ARE) gene activation and GSH biosynthesis enzyme induction (GCL, GS).

    Glutathione S-Transferase (GST) Assays
    Substrate for GST activity assays using CDNB as electrophilic co-substrate. Used to characterize GST isoform activity, xenobiotic conjugation, and Phase II detoxification enzyme kinetics.

    Ferroptosis & Redox Biology Research
    GSH is the co-substrate for GPx4 (glutathione peroxidase 4), which suppresses lipid peroxidation and ferroptotic cell death. Used in RSL3/erastin ferroptosis models to study GPx4 activity, lipid ROS accumulation, and cell death thresholds.

    • What is this product?
      Glutathione (reduced, GSH) is supplied as a crystalline free acid (CAS 70-18-8, MW 307.32 g/mol) for laboratory research use only. It is the most abundant intracellular thiol antioxidant tripeptide in mammalian cells.
    • What purity and testing methods are used?
      Each lot is tested by reverse-phase HPLC and Ellman's reagent (DTNB) thiol content verification to ≥98% purity. A lot-specific COA is included with every order, accessible via QR code on the label.
    • What are the key chemical identifiers?
      CAS 70-18-8 · EC Number 200-725-4 · Molecular formula C₁₀H₁₇N₃O₆S · MW 307.32 g/mol · Synonyms: GSH, γ-L-glutamyl-L-cysteinylglycine, L-glutathione, reduced glutathione.
    • How is glutathione reconstituted for research use?
      Dissolve in deoxygenated, acidified water (pH 3–5) at ~10 mg/mL. GSH oxidizes rapidly at neutral/alkaline pH. Prepare fresh solutions immediately before use. Do not store reconstituted solutions at neutral pH. DMSO and ethanol are not suitable solvents.
    • What is the difference between GSH and GSSG in research applications?
      GSH (reduced glutathione) is the biologically active thiol form and cellular antioxidant. GSSG (oxidized glutathione) is the disulfide dimer formed after ROS neutralization, regenerated by glutathione reductase (GR). The GSH:GSSG ratio (typically >100:1 in healthy cells) is used as a quantitative redox state indicator.
    • What is the recommended storage upon receipt?
      Store immediately at −20°C desiccated and protected from air. GSH oxidizes readily upon exposure to oxygen. Aliquot to minimize freeze-thaw cycles. Inspect for white crystalline appearance upon receipt.
    • What is a COA and why does it matter?
      A COA documents lot-specific purity (HPLC ≥98%), thiol content (Ellman's assay), and redox integrity. Thiol content verification is critical — partially oxidized GSH lots will underperform in enzymatic assays. Each lot ships with a QR-accessible COA.
