Figure 4From: Comparative analysis of three- and two-antibody cocktails to AMACR and basal cell markers for the immunohistochemical diagnosis of prostate carcinomaImmunohistochemical staining of a needle biopsy containing normal prostate tissue with the three-marker cocktail. Benign basal epithelial cells show both dark brown nuclear staining for p63 and red cytoplasmic staining for CK5. Luminal epithelial cells show no positive staining for AMACR (x 200).Back to article page
