Protein expression profile in KB/ATO cells and parental KB-3-1 cells. Expression level of (A) P-gp, (B) MRP1, (C) BCRP and (D) ABCB6 were shown in western blot results. (E) RT-PCR was performed to confirm the mRNA levels of ABCB6. Cell lysate from HEK/ABCB1, HEK/ABCC1 and HEK/ABCG2 was used as positive control for P-gp, MRP1 and BCRP respectively.
