Glutathione

Glutathione is the tripeptide γ-L-glutamyl-L-cysteinyl-glycine, a naturally occurring thiol-containing peptide. Its free sulfhydryl group makes it a standard reagent in redox, antioxidant-assay and biochemical research. Its CAS registry number is 70-18-8.

This listing supplies 1500 mg of Glutathione as a lyophilised powder, with a stated purity of >98% by HPLC. Store sealed at -20 °C, protected from light and moisture. For laboratory handling, allow the sealed vial to reach room temperature before opening to limit condensation. Reconstitute according to your validated protocol using an appropriate sterile diluent, such as bacteriostatic water, added slowly down the vial wall; swirl gently rather than shaking. Reconstituted material is normally kept at 2–8 °C and aliquoted to avoid repeated freeze–thaw cycles.

In the box: one sealed glass vial containing 1500 mg of Glutathione, closed with a rubber stopper and flip-off cap and labelled with the PeptiSource batch reference, plus one sealed 3 ml vial of bacteriostatic water. Batch documentation is available on request. For Research Use Only: supplied strictly for in-vitro laboratory research.
