erythrocyte glutathione peroxidase - an overview Red blood cell glutathione peroxidase

First using Endoproteinase Lys-C (ratio 1:33 enzyme:lysate, Alpha Laboratories) for 1 h at room temperature (24 C), after which partial digests were further diluted to 500 l with 50 mM ammonium bicarbonate (pH 7.0)

Antioxidants can inhibit exogenous and endogenous RONS as well as regulate proinflammatory cytokines, so it has potential as an immunomodulator

It's just not

Glutathione exists in redox equilibrium between disulfide (GSSG, oxidized form) and sulfhydryl (GSH, reduced form) forms and GSH levels in the living cells alter remarkably in response to the oxidative stress, which has been involved in many diseases and speeds up the aging process 5,6
