Immunofluorescence staining of MDRPs.

<p>Representative pictures of MDRP staining in HCC cell lines. The expression and localisation of MDRPs was different in the various HCC cell lines: ABCG2, LRP and MRP1 were localised on the membrane of the few groups of cells on which they were expressed, whereas PGP was mainly found in the cell cytoplasm, particularly on the membrane of intra-cellular vesicles. Nuclei stained with DAPI (blue). Original magnification 20x.
