The enzyme activity was especially prominent in the cytoplasmic globules which were assumed to be laminated 'concretions', which occur in the distal cells of the organ. It was also verified in the nuclei and in some cytoplasmic granules (lysosomes) of the proximal cells. The data indicated that lysosomes were involved with the nature or origin of the laminated concretions, but it is still questionable whether acid phosphatase activity exists in the nuclei.23-28engTriatoma infestansAcid phosphataseMalpighian tubulesArtigoWOS:000074469200002Acesso restrito6045437265946340
