The enzyme tyrosine hydroxylase (TH) was immunohistochemically localized by the peroxidase-antiperoxidase method in rat to chromaffin cells of the adrenal medulla, large neurons and small darkly staining cells of the superior cervical ganglia and noradrenergic and dopaminergic neurons in brain. As compared with the conjugated peroxidase or immunofluorescence techniques, the peroxidase-antiperoxidase method gave the most selective and specific cytoplasmic localization of TH antisera in every tissue examined. The peroxidase staining with the TH antisera was more intense in dopaminergic than in noradrenergic neurons of the central nervous system. While TH was visualized in cell bodies of both dopaminergic and noradrenergic neurons, it could only be detected in axons and terminals in the dopaminergic system. The perikarya of noradrenergic neurons could be distinguished from dopaminergic neurons by the immunohistochemical demonstration of the enzyme dopamine-beta-hydroxylase only in the former.
