Representative result of Western immunoblot analysis. Appearance of claudin-4 positivity solely in case of the biliary tract cancers (arrowheads, lanes 2,5 and 7). The position of the molecular mass marker (kDa) is indicated. The samples in lanes 1 and 4 are from hepatocellular carcinomas; lanes 3, 6 and 8 represent normal liver tissue.
