Choline analogs are not transported into uninfected erythrocytes. Effect of external choline concentration (0.0 mM, 0.05 mM, 0.5 mM, and 5 mM) on the uptake of [3H]-T16 (50 nM) or [3H]-pentamidine (50 nM) into uninfected erythrocytes over 30 minutes at 22°C. Data are mean ± SD for duplicate observations from 3 individual experiments.
