in an effort to ascertain whether a lysosomal enzyme , aryl sulphatase ( arsase ) , might share the same cell and , or , the same intracellular structure ( s ) with a histochemical golgi apparatus marker , thiamine pyrophosphatase ( tppase ) , in rat pituitary mammotrophs and somatotrophs a technique for a selective demonstration of both enzyme activities within a single specimen has been developed .
