Evaluation ROS
Cells were grown on a flat bottom black 96-well plates (Greiner
CELLSTARs). Following FA-loading, medium was replaced with
transparent DMEM containing DCFDA (Sigma Aldrich GmbH,
Germany; 10 mmol/L) and incubated (37 °C, 1 h). Cells were washed
and incubated in DMEM. After 30 min the medium was exchanged
to DMEM with or without CoCl2 and the fluorescence
(485/535 nm) was recorded for 5 h on a Paradigm™ Detection
Platform (Molecular devices, Salzburg, Austria).
