Product Overview

L-Glutathione is one of the most extensively studied low-molecular-weight antioxidant tripeptides in biochemical research. Naturally occurring within mammalian cells, it plays a central role in redox homeostasis, cellular detoxification, and immune modulation. Direct Anti Peptide offers this compound in a precision-filled sterile glass vial as a lyophilized powder, purpose-engineered to meet the rigorous demands of modern peptide research. Researchers seeking to buy a reliable, analytically verified glutathione peptide will find this product competitively positioned for both value and quality.

Peptide Structure & Amino Acid Sequence

L-Glutathione is a linear tripeptide composed of three amino acid residues: L-glutamic acid, L-cysteine, and glycine, connected by a unique gamma-peptide bond between the glutamate and cysteine moieties. Its molecular formula is C₁₀H₁₇N₃O₆S, with a molecular weight of approximately 307.32 g/mol. The thiol (-SH) group on the cysteine residue is the primary reactive site responsible for its well-documented antioxidant and nucleophilic properties, making it a subject of significant interest in oxidative stress and cellular biochemistry research.

Purity & Analytical Verification (HPLC & MS)

Every batch of L-Glutathione Peptide Vial supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm identity and purity. Reverse-phase High-Performance Liquid Chromatography (HPLC) is used to quantify peptide purity, consistently confirming results at ≥98%. Mass Spectrometry (MS) further validates the molecular identity, confirming the correct molecular weight and fragmentation pattern. These dual-verification protocols ensure that researchers receive a compound of the highest analytical standard, suitable for demanding experimental protocols.

Quality Control & Lyophilization Integrity

The lyophilization (freeze-drying) process used in the production of this peptide vial is critical to preserving structural integrity, bioactivity potential, and shelf stability. By removing moisture under controlled vacuum conditions, the lyophilized format minimizes degradation pathways associated with hydrolysis and oxidation. Each sterile glass vial is sealed under inert conditions to prevent contamination and atmospheric exposure. Batch-level quality control documentation is maintained throughout production, ensuring traceability and consistency across research applications.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained laboratory professionals operating within appropriate research environments. Standard laboratory safety protocols must be observed at all times, including the use of personal protective equipment (PPE) such as gloves, lab coats, and eye protection. The compound should be handled in a clean, controlled workspace. Avoid inhalation of powder during handling. This peptide is not approved for human or animal administration, and no safety data exists for consumptive use.

Reconstitution, Packaging & Storage

For laboratory reconstitution, researchers should consult peer-reviewed literature and institutional protocols applicable to their specific experimental design. The lyophilized powder is supplied in a sealed sterile glass vial that protects against contamination and maintains product integrity during transit and storage. Recommended storage: −20°C for long-term preservation; 2–8°C for short-term use after reconstitution. Avoid repeated freeze-thaw cycles. Protect from direct light and humidity. All handling and reconstitution procedures must comply with applicable institutional biosafety guidelines.
