Glutathione

Looking to buy glutathione? AESTX Systems supplies glutathione (GSH) as a laboratory-tested reference material with ≥99% purity and a batch-specific COA — exclusively for research purposes.

Glutathione (GSH, γ-L-glutamyl-L-cysteinyl-glycine) is the most important intracellular antioxidant in mammalian cells. In cell biology research, glutathione is studied in relation to oxidative stress, detoxification mechanisms and cellular redox homeostasis.

Research areas for glutathione (GSH)

Oxidative stress & redox research

Used in cell culture models to investigate responses to reactive oxygen species (ROS), lipid peroxidation and oxidative DNA damage.

Detoxification research (phase II metabolism)

As a substrate for glutathione S-transferases (GST), it is central to in vitro studies of hepatic detoxification and xenobiotic conjugation.

Mitochondrial function research

Mitochondrial glutathione (mGSH) is described in research models of mitochondrial membrane integrity and apoptosis regulation.

Immunomodulation research

Studied in lymphocyte cell cultures to investigate T-cell function and immunological redox signalling pathways.

Anecdotal note: Reports from the research community describe a strong interest in antioxidant and detoxification research questions. These reports are not scientifically substantiated and relate exclusively to research settings.

Buy glutathione from AESTX Systems

Looking to buy glutathione? AESTX Systems supplies Glutathione (GSH) as a lab-tested reference material with an HPLC-confirmed purity of ≥ 99 %. Every batch is analytically tested for purity and identity and supplied with a batch-specific certificate of analysis (COA). The material is intended exclusively for research and laboratory use.

Forms of glutathione in research

Research distinguishes between several forms. The reduced glutathione (GSH) is the biologically active form and the most important intracellular antioxidant, while the oxidised form (GSSG) exists as a disulfide. The GSH-to-GSSG ratio is considered a key marker of cellular oxidative status in redox studies. The name L-glutathione also refers to the naturally occurring tripeptide consisting of L-glutamic acid, L-cysteine and glycine.

Why choose glutathione from AESTX Systems?

• ≥99% purity — every batch analysed by HPLC for purity and identity
• Batch-specific COA — complete certificate of analysis with every delivery
• Reduced glutathione (GSH) — as a high-purity reference material for laboratory applications
• Shipping from Germany — fast, discreet delivery within Germany and to Austria
• Research Use Only — appropriate declaration and documentation as a reference substance

Quality, specifications and storage

Research and educational institutions looking to obtain glutathione in Germany as a reference material receive consistently documented quality from AESTX Systems. Purity of ≥99% is determined by high-performance liquid chromatography (HPLC); identity and molecular weight are analytically confirmed. In research practice, glutathione reference material is described as being stored in a cool, dry place protected from light, since the reduced tripeptide is sensitive to oxidation. All purity, batch and specification information can be traced through the accompanying COA.

Frequently asked questions about buying glutathione

What is the purity of glutathione from AESTX Systems?
The glutathione (GSH) offered has an HPLC-confirmed purity of ≥99% and is supplied with a batch-specific Certificate of Analysis.

How does reduced glutathione (GSH) differ from the oxidised form?
Reduced glutathione (GSH) is the free, active form; the oxidised form (GSSG) consists of two molecules joined by a disulfide bond. The GSH/GSSG ratio is an important parameter in redox research.

Who is the product intended for?
Glutathione is intended exclusively for research and laboratory use by qualified research and educational institutions and appropriately knowledgeable individuals.

Glutathione in cellular and longevity research

Beyond traditional redox and detoxification research, Glutathione is used as a reference substance in numerous other in vitro models. These include investigations of cellular senescence, protein folding in the endoplasmic reticulum and the regulation of signalling pathways that respond to cellular redox status. In longevity and anti-ageing research, the GSH/GSSG ratio is an established marker for describing the antioxidant capacity of cellular systems over time. AESTX Systems supplies glutathione with documented purity of ≥99%, making it suitable as a reliable reference material for reproducible experimental conditions. Anyone looking to buy glutathione receives an analytically characterised substance with a traceable batch history.
