Figure 3

Effects of GGT inhibition on transferrin-bound iron uptake in K562 cells. Online fluorimetric monitoring of intracellular iron levels. Transferrin (>70% iron-saturated) was added where indicated, and the decrease in fluorescence of intracellular calcein was recorded (cfr. Methods for details of the procedure). One representative experiment out of five is reported.
