Although,SA-β-gal activity was detected mostly in the periphery of the sections, leaving the core of the tissue unstained (likely due to slow penetration of the SA-β-gal stain into the tissue) a clear co-localization of SA-β-gal activity and SBB staining was noted close to the tissue periphery marked by pathological features of BPH.
