Glutathione (GSH) and glutathione disulfide (GSSG) form the principal thiol redox couple in the endoplasmic reticulum (ER); however, few studies have attempted to … WebJul 25, 2024 · In this manner, GSH could be oxidized to GSSG with a generated reactive oxygen species (e.g., H 2 O 2 ). Subsequently, the formed GSSG was electrochemically reduced at the electrode surface to produce a measurable signal ( Fig. 2, upper panel). Using a DPV method, an extraordinarily low LOD (100 nM) was obtained even with the …
WebJul 29, 2024 · Oxidation of the reduced form of glutathione based on the 1:1 copper(Cu +2)-glutathione(GSH) complexes was found to occur at a decreased overpotential at a glassy carbon electrode modified with highly ordered mesoporous silica thin films (MSTFs) by means of the electrochemically assisted self-assembly (EASA) process.Adsorption of … WebAs displayed in Fig. 3 B, oxidized [email protected] Zr-based MOFs could oxidize TMB (red line), while GSH acted as an effective antioxidant to block the above oxidation process, resulting in the reduction of the UV absorption intensity (green line). Catalyzed by GST, GSH forms a product of CDNB-SG with 1-chloro-2,4-dinitrobenzene (CDNB), which ...
