Single frontal displacement studies of 8 compounds (4.25 μM), including etoposide, for the BCRP carried out on both CMAC(LN-229)-OT and NMAC(LN-229)-OT using ammonium acetate [10 mM, pH 7.4] in the presence of 2 μM verapamil and 0.75 μM etoposide as the mobile phase. The data was normalized to the change in breakthrough volume observed with etoposide and the relative changes from etoposide (0%) are reported.
