## Description

Research-grade Glutathione 1200mg lyophilised powder — 99.0% HPLC purity, COA verified. The body's primary intracellular antioxidant — high-dose format for oxidative stress, redox biology, liver detoxification, and cellular protection research.

## Detailed Overview

**Antioxidant and Cellular Protection Research**

Glutathione is available in Australia from Peptide Warehouse Australia with fast domestic shipping to all states and territories.

Glutathione is the most abundant endogenous antioxidant in mammalian cells. Found in virtually every cell type, it acts as the cell's primary defence against oxidative damage — neutralising reactive oxygen species and playing a central role in hepatocyte redox biology (Lu, Biochim Biophys Acta 2013). In research, it is used to study cellular oxidative stress responses, hepatocyte toxicity models, and how antioxidant capacity changes in disease and ageing models. The 1200mg high-dose format is designed for extended cell culture work, large-scale assays, and research programmes with high throughput requirements.

**What Glutathione Is Studied For**

**Oxidative stress protection** — The primary research application: used to study how cells defend against free radical damage and how antioxidant capacity relates to cell health and survival.
**Hepatocyte and liver biology** — A central molecule in liver biology; studied in hepatocyte models of drug-induced toxicity and detoxification enzyme systems.
**Immune cell biology research** — Used in lymphocyte, NK cell, and macrophage research to study the relationship between antioxidant status and immune cell activity.
**Neuroprotection** — Studied in brain cell models of oxidative damage; brain tissue is especially vulnerable to oxidative stress due to its high energy demands.

## Frequently Asked Questions

### What is Glutathione and why is it important in research?

Glutathione (L-Glutathione, GSH, CAS 70-18-8, MW 307.32 Da, molecular formula C₁₀H₁₇N₃O₆S) is a tripeptide (γ-Glu-Cys-Gly) and the most abundant intracellular antioxidant in human cells. Its core function is to neutralise reactive oxygen species (ROS) by donating electrons via its cysteine thiol group. It is regenerated from the oxidised form (GSSG) by glutathione reductase using NADPH — forming the glutathione redox cycle. In research, glutathione is used in oxidative stress models, detoxification assays, cell viability studies, neuroprotection experiments, immune cell function research, and as a reference compound in redox biology. It is one of the most fundamental tools in cellular biochemistry. For research use only.

### What is the difference between reduced glutathione (GSH) and oxidised glutathione (GSSG)?

GSH (reduced glutathione) is the active antioxidant form with a free thiol group (-SH) on the cysteine residue. It donates electrons to neutralise ROS and is regenerated by glutathione reductase. GSSG (oxidised glutathione) is the disulphide-linked dimer formed when two GSH molecules donate electrons. The GSH:GSSG ratio is the primary cellular redox state marker — a high ratio indicates a healthy, reduced cellular environment; a low ratio indicates oxidative stress. Our product is the reduced form (GSH). For accurate redox research, reconstituted GSH should be stored under inert conditions to minimise spontaneous oxidation to GSSG. Not for human consumption — for research use only.

### Why does glutathione oxidise and how do I prevent it?

GSH oxidises spontaneously when its thiol group reacts with atmospheric oxygen to form GSSG. This is accelerated by heat, light, metal ion catalysts (Cu²⁺, Fe³⁺), alkaline pH, and air exposure. To minimise oxidation: store lyophilised powder at −20°C in the dark; reconstitute only the volume needed; acidify the solution to pH 5–6 if protocol allows; store reconstituted solution under nitrogen gas if possible; avoid repeated freeze-thaw cycles. For in-vitro assays, prepare fresh working solutions on the day of the experiment. Yellowing of the reconstituted solution indicates oxidation — discard if colour has changed. Not for human consumption — for research use only.

### What research models commonly use glutathione?

Glutathione is used across many in-vitro and in-vivo research models: hepatocyte toxicity and drug-induced liver injury assays (DILI models); glutathione S-transferase (GST) enzyme activity assays; lymphocyte proliferation and NK cell activity studies; GSSG/GSH ratio measurement by DTNB assay or LC-MS/MS; neuronal oxidative damage models (Parkinson's, Alzheimer's preclinical models); cardiomyocyte ischaemia-reperfusion injury experiments; skin cell UV-radiation damage models; and mitochondrial glutathione (mGSH) research in ageing. It is also used as a positive control in antioxidant capacity assays (ORAC, FRAP, ABTS). Not for human consumption — for research use only.

### How do I reconstitute and store Glutathione 1200mg?

Reconstitution: Glutathione is highly water-soluble. Draw the required volume of bacteriostatic water and inject slowly into the vial; swirl gently. For a 1200mg vial: 12mL BAC water = 100mg/mL; 24mL = 50mg/mL. Reconstituted glutathione is susceptible to oxidation — work quickly, minimise air exposure, store in the dark at 2–8°C, and use within 2 weeks. For long-term storage of reconstituted solution, aliquot into single-use volumes and freeze at −80°C under inert gas where possible. Discard if the solution has yellowed. Not for human consumption — for research use only.

### Is Glutathione legal to buy in Australia for research?

Glutathione is legal to purchase in Australia for legitimate laboratory research purposes. As an endogenous tripeptide synthesised naturally in mammalian cells, it is not a scheduled substance when sold for research use. Purchasers must confirm research-only use. Our Glutathione 1200mg is supplied as a research compound with 99.0% HPLC purity and full COA documentation. Peptide Warehouse Australia dispatches nationwide from our Melbourne warehouse via Australia Post. Not for human consumption in this lyophilised research form.

### What is the difference between reduced and oxidised glutathione in research?

Glutathione exists in a reduced (GSH) and an oxidised (GSSG) form, and the GSH/GSSG ratio is a widely used research marker of cellular redox state. Research-grade glutathione is studied as the master intracellular antioxidant in oxidative-stress models. Not for human consumption — for research use only.

### What research areas involve glutathione?

Glutathione is studied across oxidative-stress, detoxification and cellular-redox research, where it participates in neutralising reactive oxygen species and supporting phase-II conjugation pathways in cell models. These are mechanistic research contexts, not evidence of any human benefit. Not for human consumption — for research use only.
