The tripeptide glutathione (gamma-glutamylcysteinylglycine; GSH) is the predominant low molecular mass thiol in cells. The function of GSH is of considerable interest, with the molecule being implicated in numerous cellular processes in addition to being a major cellular antioxidant. The enzyme glutamate-cysteine ligase (GCL) is the rate-limiting step in GSH synthesis. The GCL assay described here is based on high-performance liquid chromatography and exploits the electrochemically active… Expand
