In rabbit heterophils, acid phosphatase activity occurs in primary (azurophil) granules which predominate in early cells and persist in mature cells and in tertiary granules which are seen only in mature cells. Alkaline phosphatase activity occurs in secondary granules which appear in intermediate heterophils and later predominate in mature cells. Acid phosphatase activity in heterophil Golgi zones coincides developmentally with the genesis of primary and, later, tertiary granules, whereas alkaline phosphatase in the Golgi complex coincides with secondary granulogenesis. In developing eosinophils, acid phosphatase reaction product occurs in Golgi elements, rims the spherical precursors of angular, mature granules and appears inconsistently within mature granules. Basophil myelocytes show acid phosphatase in Golgi elements but not in specific granules. Additional acid phosphatase reactive structures include: granules of mononuclear cells; phagocytic vacuoles in macrophages; autophagic vacuoles in maturing erythroid cells; small dense granules of platelets; dense bodies in lipocytes; and Golgi elements of mononuclear cells, macrophages, nucleated red cells, megakaryocytes and lipocytes. Localized deposits were absent in control specimens except for enzyme-independent nuclear staining in alkaline phosphatase preparations.

In the prolactin cell of the eel adenohypophysis acid phosphatase activity occurs within the majority of the Golgi cisternae and developing secretory granules. Acid phosphatase is also present within larger membrane-bound bodies, most of which are similar to the lytic dense bodies described in other cell types. In discussing the functional significance of this enzyme distribution particular attention is paid to its association with the secretory mechanisms of the prolactin cell.
