FIG. 1.

Expression of various claudins in bona fide HCV target cells. Human hepatoma or primary cells, as indicated at the top of the blots (Hepat., hepatocytes), were analyzed by Western blotting. Membranes were probed using antibodies against the proteins indicated to the right of the blots. To control for the amount of protein loaded per well, membranes were stripped with a Re-Blot Western blot kit (Chemicon International) and reprobed with antibodies against β-tubulin or actin for PBMC and hepatocytes.
