Figure 7. Kinetic analysis of system xc− in wild type and Hfe−/− RPE cells.
(A) Saturation kinetics of glutamate uptake in wild type and Hfe−/− RPE cells was evaluated by monitoring the uptake in a Na+-free medium with varying concentrations of glutamate. (B) Eadie-Hofstee transformation of the data. The experiment was repeated three times.
