Differential Rates of Glutathione Oxidation for Assessment of Cellular Redox Status and Antioxidant Capacity by Capillary Electrophoresis-Mass Spectrometry: An Elusive Biomarker of Oxidative Stress

Glutathione metabolism plays a fundamental role in maintaining homeostasis and regulating the redox environment of a cell. Despite the widespread interest in quantifying glutathione metabolites in oxidative stress research, conventional techniques are hampered by complicated sample handling procedures to prevent significant oxidation artifacts generated during sample collection, sample pretreatment, and/or chemical analysis. In this report, a …
