    L-Glutathione reduced
    Product name: L-Glutathione reduced Synonyms: GSH INCI name: Glutathione CAS No.: 70-18-8 EINECS: 206-169-9 Quality: assay 98% up by HPLC Molecular formula:C10H17N3O6S Molecular weight: 307.32   Description: L-Glutathione (GSH) reduced has been used in the elution buffer to elute GST (glutathione S-transferase)-fused proteins using glutathione-agarose beads. It has been used to prepare a standard curve for GSH analyses. May be used at 5-10 mM to elute glutathione S-transferase (GST) from glutathione agarose.   Glutathione is an antioxidant produced in cells. It’s comprised largely of three amino acids: glutamine, glycine, and cysteine.   Glutathione levels in the body may be reduced by a number of factors, including poor nutrition, environmental toxins, and stress. Its levels also decline with age.   In addition to being produced naturally by the body, glutathione can be given intravenously, topically, or as an inhalant. It’s also available as an oral supplement in capsule and liquid form. However, oral ingestion of glutathione may not be as effectiveTrusted Source as intravenous delivery for some conditions.   Glutathione benefits 1. Reduces oxidative stress 2. May improve psoriasis 3. Reduces cell damage in alcoholic and nonalcoholic fatty liver disease 4. Improves insulin resistance in older individuals 5. Increases mobility for people with peripheral artery disease 6. Reduces symptoms of Parkinson’s disease 7. May help fight against autoimmune disease 8. May reduce oxidative damage in children with autism 9. May reduce the impact of uncontrolled diabetes 10. May reduce respiratory disease symptoms         Specification (USP43): Items Standards Appearance White or almost white crystalline powder Appearance of Solution Clear and colorless (10% w/v in water) Bulk Density ≥0.40g/ml Tapped Density ≥0.60g/ml Mesh Size 100% thru mesh 80 Identification S.O.R: -15.5°~-17.5°   Infrared: Positive Related Substances L-glutathione oxidized ≤1.5%   Total impurities ≤2.0% Assay (dry basis) 98.0%~101.0% Loss on Drying (3h at 105℃) ≤0.5% Residue on Ignition ≤0.1% Ammonium ≤200ppm Chloride ≤200ppm Sulfate ≤300ppm Iron ≤10ppm Arsenic ≤1.0ppm Cadmium ≤0.2ppm Lead ≤0.5ppm Mercury ≤0.3ppm Heavy Metals ≤10ppm Total Plate Count ≤1000cfu/g Yeast & Mold ≤100cfu/g Coliforms Negative/1g E.Coli Negative/10g Salmonella Negative/10g Staphylococcus Aureus Negative/10g         Specification (EP10): Items Standards Appearance White or almost white, crystalline powder or colorless crystals Solubility Freely soluble in water, very slightly soluble in ethanol and in methylene chloride Identification S.O.R.:-15.5°~-17.5°   Infrared: Conforms to the Reference Spectrum Appearance of solution Clear and colorless Specific optical rotation -15.5°~-17.5° Related substances -Impurity A (L-cysteinylglycine)≤0.5%   -Impurity B (Cysteine)≤0.5%   -Impurity C (L-glutathione oxidised)≤1.5%   -Impurity D (L-γ-glutamyl-L-cysteine)≤1.0%   -Impurity E (Product of degradation)≤0.5%   Total Impurities≤2.5% Chlorides ≤200ppm Sulphates ≤300ppm Ammonium ≤200ppm Iron ≤10ppm Heavy Metals ≤10ppm Loss on Drying ≤0.5% Sulfated ash ≤0.1% Bacterial Endotoxin ≤0.1EU/mg Assay 98.0% to 101.0%       Production capacity: 1000kg/month Storage condition: Stored in cool, dry place, room temperature.

    L-Glutathione oxidized
    Product name: L-Glutathione oxidized Synonyms: GSSG INCI name: oxidized Glutathione CAS No.: 27025-41-8 EINECS: 248-170-7 Quality: assay 98% up by HPLC Molecular formula:C20H32N6O12S2 Molecular weight: 612.63   Description: Glutathione can occur in reduced (GSH), oxidized (GSSG), or in mixed disulfide forms and is ubiquitous in multiple biological systems serving as the major thiol-disulfide redox buffer of the cell. Glutathione, Oxidized (GSSG) is the oxidized version of the naturally occurring and very important antioxidant glutathione (GSH). In vivo GSSG is reduced back to GSH via the NADPH-dependent enzyme glutathione reductase. The ratio of GSH to GSSG is often used to gauge the level of oxidative stress in cells, with higher concentrations of GSSG implying more oxidative stress, therefore beeing an important bioindicator of cellular health. GSSG functions as a hydrogen acceptor in the enzymatic determination of NADP+ and NADPH and can be a proximal donor in S-glutathionylation post translational modifications. GSSG, along with glutathione and S-nitrosoglutathione (GSNO), have been found to bind to the glutamate recognition site of the NMDA and AMPA receptors (via their γ-glutamyl moieties), and may be endogenous neuromodulators. GSSG can be used as substrate for enzymatically assaying glutathione reductase.     Specification (assay 98% up by HPLC): Items Standards Appearance White crystalline powder Odor Odorless to faint odor Identification (IR) Pass test Identification (HPLC) Pass test State of solution Colorless to yellowish clear Specific rotation (at 25℃) -103° to -93° Heavy metal (As Pb), mg/kg ≤20 Moisture, % ≤6.0 Residue on ignition, % ≤0.5 Ethanol, % ≤0.05 Single unknown impurity ≤1 Total unknown impurity ≤2 Total unknown impurity ≤4 Total plate count, cfu/g ≤100 Assay, % ≥98.0     Production capacity: 1000kg/month Storage condition: Stored in cool, dry place, room temperature.
