title: Localization of acid phosphatase in the principal cells of the guinea pig epididymis.
abstract: The activity of acid phosphatase in the principal cells of the guinea pig epididymis was studied histochemically. The enzyme activity was localized in the Golgi and apical regions in segments 1-4. In segments 5-7, the enzyme activity was distributed throughout the entire supranuclear cytoplasm. There was a gradual increase of acid phosphatase activity from segments 1-7. A possible function of acid phosphatase in the epididymis is discussed.
