The eluted protein was digested overnight with thrombin, followed by anion-exchange chromatography (HiTrap Q FF, Cytiva), and finally polished by SEC using a Superdex 200 column (HiLoad 16/600, Cytiva)
This is also why injecting glutathione subcutaneously is the easiest means of administering the peptide in adequate doses, albeit multiple injections are required to achieve therapeutic levels of GSH support
