Laminin induces the expression of cytokeratin 19 in hepatocellular carcinoma cells growing in culture

Figure 2 Western blotting for CK18, CK7 and CK19 using the intermediate filament cytoskeleton extracts from HCC cell lines SMMC7721 (A), HCC-9204 (B), HepG2 (C), HHCC (D) and HCC-9724 (E). Immunoreactions were demonstrated by AP-labeled anti-mouse IgG and visualized in a BCIP/NBT solution. The right lanes show molecular weight standards (MWS) visualized by staining with Commassie R250, with three indicated by the short bars (from top to bottom, M_r62000, M_r47500 and M_r32500, respectively).
