A. 0.01 μg/ml ART was added to the RPMI cell culture medium containing 0.1 % hematocrit. After 4 h ART incubation, the iRBC velocities with and without ART treament were compared. B. 0.01 μg/ml ART was added to the RPMI cell culture medium containing 0.1 % hematocrit. After 2, 4, and 6 h ART incubation, the iRBC velocities were compared. C. Time dependent ART effects on uRBC velocities were studied. D. 0.01, 0.05 and 0.10 μg/ml ART was added to the RPMI cell culure medium containing 0.1% hematocrit. After 4 h ART incubation, the concentration dependent ART effects on iRBC velocities were compared. Black and red dots denote uRBCs and iRBCs without ART treatment whereas black and red circles denote uRBCs and iRBCs with ART treatment respectively. Velocity measurement on every experimental day is normalized against the average uRBC velocity in the control sample.
