Figure 3: Rohdamine-123 uptake in rifampin treated or untreated LL-CPK1 cells. Cells were treated with 25 μM rifampin containing medium for a week. Thereafter, rohdamine-123 (10 μM) uptake was measured at different time points. Data are expressed as percent uptake relative to cells exposed to rifampin-free medium (with rifampin-free incubations being equivalent to 100%). Differences were assessed using unpaired two-tailed student t-test. * represent significant difference between rifampin-treated and untreated cells.
