WebTo assay the intracellular ROS production, HT22 cells were seeded on glass coverslip slides and lodged in 6-well plates. After appropriate stimulation with erastin, cells were loaded with 10 µM 2,7-dichlorodihydro-fluorescein diacetate for 10 minutes (CM-H2DCFDA, Thermo Fisher Scientific, Schwerte, Germany). WebThese stock solutions were further diluted in assay media to obtain the required test compound concentration and to restrict DMSO to a maximal concentration of 1% (v/v). Unused portions of the stocks were stored at −20°C. The composition of IC consisted of 100 µM thiamine, 50 µM L-cystine, 1 µM calcium D-pantothenate, and 1 µM folic acid.
