Product Detail

Brief Overview

Glutathione (abbreviated GSH, reduced form) is synthetic tripeptide freeze-dried solid raw material produced by standardized solid-phase amino acid condensation synthesis, multi-stage reversed-phase chromatographic purification, desalting and low-temperature vacuum freeze-drying processes. It is only supplied for closed in-vitro basic academic laboratory research of universities, biomedical research institutions and biotechnology R&D teams, covering cell redox balance testing, intracellular antioxidant pathway exploration, detoxification enzyme cofactor mechanism analysis, oxidative damage cell model construction and multi-organ tissue slice co-culture biochemical pathway research. The finished product is uniform white crystalline freeze-dried powder with stable thiol molecular structure, which can retain complete biological activity and highly repeatable experimental data during long-term continuous cell strain passaging and organ slice incubation. Multiple vacuum-sealed neutral borosilicate glass vial specifications are available to match various laboratory testing schemes: 100mg, 500mg, 1g, 5g. Each production batch is equipped with complete technical documents including independent batch inspection reports and unified technical datasheets, only for internal laboratory filing and academic reference.

Core Laboratory Research Application & Functional Characteristics

Strict Usage Restriction Statement

Exclusive Research Advantages

Stable Thiol Active Group Molecular Feature

The complete γ-glutamyl-cysteinyl-glycine tripeptide chain carries intact free thiol (-SH) active group, which can stably participate in intracellular redox reaction cycles inside experimental containers, and serves as a standard reference substance for cellular antioxidant pathway research. It provides low-interference, single-variable comparison data for tripeptide-redox interaction and cell metabolic signal research, effectively eliminating multiple confounding interference factors in parallel control cell groups.

Superior Long-Term Structural Stability After Lyophilization

Low-temperature vacuum dehydration locks the complete linear tripeptide skeleton and free thiol active group structure, preventing disulfide bond cross-linking oxidation, peptide chain hydrolysis and non-specific molecular aggregation during storage and cross-border transportation. Synthetic amino acid chain structure can resist degradation by intracellular proteases, solving the defect of rapid loss of biological activity of liquid medium samples, greatly reducing the workload of repeated reagent preparation for long-term laboratory inventory management and continuous cell passaging experiments, and supporting multi-day uninterrupted cell culture experimental schemes without frequent medium replenishment.

Wide Compatibility With Conventional Mammalian Cell Culture Systems

This freeze-dried powder can be fully dissolved in laboratory dedicated bacteriostatic purified water and neutral PBS buffer solution with adjusted pH value. It is compatible with conventional fibroblasts, endothelial cells, mesenchymal stem cells, liver precursor cells and multi-tissue slice testing systems, will not introduce foreign pollutants that interfere with the cell growth microenvironment, and will not trigger abnormal cytotoxic reactions within the standard research concentration range.

Stable Concentration Gradient Response Characteristics

Adjustable working concentrations adapt to customized experimental designs; multiple detection indicators including antioxidant enzyme synthesis level, intracellular free radical content and cell proliferation ratio show stable linear changes with concentration gradients, facilitating quantitative data statistics and academic paper graph drawing for basic tripeptide redox signal research.

Ultra-Low Background Interference For Detection Analysis

Multi-stage layered reversed-phase chromatographic purification removes residual truncated peptide fragments, incomplete synthesis by-products, free amino acid impurities and endotoxin pollutants in finished solid products. It will not generate extra noise signals for spectrophotometers, fluorescence detectors and cell proliferation colorimetric testing equipment, delivering reliable and clear biochemical quantitative detection results and stable repeatability for cell antioxidant signal verification experiments.

Consistent Batch Performance Across All Production Batches

The integrated standardized production process including solid-phase tripeptide synthesis, multi-step chromatographic purification and vacuum freeze-drying ensures unified tripeptide purity, thiol group integrity and redox signal regulation performance of all batches. It avoids experimental result deviations caused by inconsistent raw material synthesis batches, supporting parallel control experiments and repeated result verification for laboratory teams engaged in cellular oxidative metabolism signal research.

Standard Step-by-Step Dissolving Operation Guidance

Recommended Matching Solvent Medium: Laboratory dedicated bacteriostatic purified water / pH 6.8–7.4 neutral PBS buffer

Slowly inject the prepared buffer medium along the inner wall of the glass vial to avoid violent foaming and tripeptide thiol group oxidative denaturation
Fully tighten the vial cap, rotate and swirl gently in slow circular motions for 3–5 minutes until all freeze-dried solid powder is completely dissolved (the reduced tripeptide has slight hygroscopicity, slow and gentle dissolution is required to prevent incomplete solvation and thiol oxidation by air)
Do not violently agitate the container; intense stirring will trigger rapid contact between thiol group and air oxygen, irreversible disulfide cross-linking, and permanent attenuation of redox biological activity

Suggested Working Concentration Range For Cellular Antioxidant & Oxidative Stress Cell Model Basic Research

0.1 μM – 10 mM, flexibly adjustable according to customized experimental design, cell strain categories and test endpoint detection indicators

Storage Environment & Valid Usage Cycle Specifications

Unopened Original Vacuum-Sealed Vials

Long-term sealed storage condition: Store fully sealed vials at -20℃, completely shielded from direct sunlight and high ambient humidity (photosensitive and easily oxidized tripeptide must avoid repeated exposure to humid air and strong light irradiation)

Valid stable storage period under constant -20℃ freezing environment: 24 months

Short-distance transportation stability tolerance: It can retain complete redox biological activity for up to 7 days under ambient temperature ≤25℃, and light-proof packaging must be used during transportation

Forbidden storage operations: Frequent repeated temperature cycle fluctuations, long-time continuous direct sunlight exposure, storage beside volatile oxidizing organic chemical reagents, repeated opening of sealed vials in humid atmospheric environment

Liquid Mixed With Bacteriostatic Purified Water / PBS Buffer After Full Dissolution

Storage condition after complete dissolution: Place in a refrigerator at 2℃ ~ 8℃ environment, fully shaded from light and tightly sealed

Suggested full consumption time limit: Use up all mixed liquid within 30 days after preparation completion

Strict prohibition rule: Do not repeatedly freeze and thaw the diluted mixed liquid; repeated freeze-thaw cycles will accelerate thiol oxidation, permanently damage the tripeptide skeleton and coordination stability, completely losing the redox signal regulation activity required for cellular antioxidant cell culture research
