2026 FDA Peptide Reclassification Explained

Beyond direct antioxidant activity, glutathione functions through several enzymatic systems central to detoxification and redox control, including glutathione-S-transferases for conjugation reactions, glyoxylases, glutathione peroxidases and peroxiredoxins for peroxide reduction, and glutaredoxins for thiol-disulfide exchange

GST protein has a strong binding affinity for glutathione, immobilized on agarose and when a mixture of proteins is added to this matrix, the protein of interest (tagged to GST) binds to the glutathione ligand and impurities are removed by washing.Finally, the beads are treated with reduced glutathione (free) which competitively detaches the interaction between immobilized glutathione and the GST-tagged protein of interest from the beads which results in a purified protein.
