WebApr 13, 2024 · Glutathione redox ratio. Glutathione (γ-L-glutamyl-L-cysteinyl-glycine) is the main endogenous, cellular, thiol-based antioxidant existing in reduced (GSH) and oxidized (GSSG) forms. In healthy cells, the ratio of GSH:GSSG is actively kept higher than 100:1 but different stress-conditions can affect this balance thus it can be used as a ...
WebThiol compounds including predominantly glutathione (GSH) are key components of redox homeostasis, which are involved in the protection and regulation of mammalian cells. The assessment of cell redox status by means of in situ analysis of GSH in living cells is often preferable over established assays in cell lysates due to fluctuations of the GSH pool.
