Glutathione

Reduced glutathione (GSH). 1.5 g per vial. Glutathione is supplied as a lyophilised solid at a 1500 mg fill, sealed in amber borosilicate with an argon headspace.

Our Six-Step protocol applies identically to tripeptides and tetrapeptides: SPPS synthesis, HPLC purification to ≥ 99%, and ESI-TOF mass confirmation. Copper complexes additionally pass a UV-vis coordination check. Every lot ships with a CoA signed by a third-party analytical lab.

Sealed vials hold indefinitely at −20 °C. Short peptides are robust as dry solids; in aqueous solution, HPLC purity remains within spec for approximately four weeks under refrigeration.
