Figure 3. Western blot for the P-gp protein in the parental human prostate cancer cell lines (DU-145 and 22Rv1) and their docetaxel resistance clones (DU-145DOC10 and 22Rv1DOC8). The size of the P-gp protein is indicated by an arrow (130-180 kDa). The lower panel shows equal load by β-actin staining (45 kDa, arrow). P-gp: P-glycoprotein.
