Representative histological section and low power view of EpCAM stained whole-mount human prostate showing staining of normal epithelium, tumor cells, and tumor associated stroma. The primary anti-EpCAM antibody was titrated to provide clean staining of normal epithelium (regions outside of box). At this antibody concentration, intense EpCAM staining of tumor regions (due to both epithelial tumor cells and tumor stroma) was observed as indicated by the box in the figure.
