Cathepsin D Expression in Colorectal Cancer: From Proteomic Discovery through Validation Using Western Blotting, Immunohistochemistry, and Tissue Microarrays
Figure 3
Representative CRC tissue for intensity scoring of tissue microarray immunohistochemistry (DAB substrate, brown). None or weak expression of cathepsin D (a) was scored 1. (b) Moderate expression of cathepsin D in tumor cells was scored 2 and strong expression of cathepsin D (c) was scored 3. Tissue sections were counterstained with haematoxylin (blue) (20x objective).
