Immunohistochemical analyses of SHH expression levels in nonmalignant prostate and adenocarcinoma tissues. Immunohistochemical analyses of SHH expression levels in nonmalignant prostate and adenocarcinoma tissues. AccuMax array sections of normal and malignant prostate tissue samples were probed with anti-SHH antibody after blocking with serum. All sections were examined under a microscope, and the immunoreactivity was judged by dark brown staining. Representative pictures of stained tissue samples of normal prostate and adenocarcinoma obtained at original magnifications of ×100, ×200, and ×400. Murielle Mimeault et al.
