Immunostaining of hnRNP A2/B1 in human liver tissue samples. Tissue samples were incubated with a commercial goat polyclonal anti-human hnRNP A2/B1 specific antibody and visualized using diaminobenzidine. (A) Human normal liver tissue showing negative staining (×20). (B) Hepatitis tissue sample showing positive staining of the hepatocyte nuclei (Marked N) (×20). (C) HCC tissue sample showing a nuclear staining pattern (Marked N) (×20). (D) HCC tissue sample showing both cytoplasmic (Marked C) (long arrow) and nuclear staining (Marked N) (short arrow) within discrete cell clusters (×20). (E) HCC tissue sample showing cytoplasmic staining patterns (Marked C) (×20). (F) HCC tissue sample showing a cytoplasmic staining pattern. The cell nuclei have been counterstained with hematoxylin (Marked C) (×10).
