The involvement of reactive metabolites in cancer and cellular necrosis has been well established. The nucleophile, glutathione, provides a major mechanism of intracellular protection from electrophilic metabolites. Conjugation with glutathione to generate stable, water-soluble metabolites has been utilized to determine the nature and rates of formation of precursor reactive metabolites. In addition, because activities of the glutathione transferases may play a key role in tissue/cellular susceptibilities to electrophilic compounds, measurement of catalytic activities of these proteins can play an important role in discerning the underlying mechanisms of cell-selective toxicities. This unit outlines HPLC methods found to provide good separation of glutathione conjugates and includes two additional procedures that can be utilized in experiments where high throughput assays are needed for measuring transferase activities.
