Figure 2
Validation of cathepsin D expression at two different regions, main tumor body. (MTB) and invasive front (IF) area of primary tumor and liver metastasis (LM) from the same patient by immunohistochemistry (IHC) (DAB substrate, brown). Sections were counterstained with haematoxylin (blue) (20x objective).
