Overview
Glutathione (γ-L-glutamyl-L-cysteinylglycine) is a tripeptide in which glutamate is joined to cysteine through its side-chain γ-carboxyl group rather than the usual α-peptide bond, which protects it from most peptidases. Its cysteine thiol is the reactive center: in the reduced form (GSH) it donates electrons and is oxidized to the disulfide-linked dimer (GSSG). Supplied in the reduced form (CAS 70-18-8) as a lyophilized solid for laboratory research use only.
In research settings, glutathione is used as a substrate and cofactor in assays of glutathione peroxidase, glutathione S-transferase and glutathione reductase, and as a reference standard in measurements of the GSH/GSSG ratio, the most widely used index of cellular redox state. It is studied in models of oxidative stress, xenobiotic conjugation, protein S-glutathionylation and immune-cell redox signaling. This material is supplied strictly for in vitro and laboratory research applications and is not intended for human or veterinary use.

Handling & storage
Store lyophilized powder at -20C, protected from light and moisture. The reduced thiol oxidizes in air and in the presence of moisture; keep the vial sealed until use.
