|Figure 4: Rohdamine-123 uptake in rifampin-free (A) or rifampin-treated (B) LL-CPK1 cells. Cells
were exposed to either medium-only or 20 % NL or 20% HL serum for 24 h and then rohdamine-123
(10 μM) uptake was measured. Data are expressed as percent uptake relative to cells
exposed to rifampin-free medium-only (equivalent to 100%). One way analysis of variance
followed by Dunn's test or Holm-Sidak test were used to assess differences among the
groups at each time point. Breaks between horizontal lines above data bars denote
significant differences from other data point(s).
