Dissecting redox biology using fluorescent protein sensors
GS-CAM - d 15 T PP, bis trifluoroacetate salt Glutathione (26.0 mg, 85 mol, 1.1 eq) was added to a solution of IAM- d 15 TPP iodide 40 (51.0 mg, 0.077 mmol, 1.0 eq) and triethylamine (35 mL, 0.255 mmol, 3.0 eq) in methanol (1.0 mL)
8 Glutathione (GSH) is a crucial intracellular antioxidant, a tripeptide (-glutamyl-cysteinyl-glycine) (Figure 1), and plays a key role in maintaining cellular redox balance
