Immunofluorescent analysis of Tyrosine Hydroxylase using a Tyrosine Hydroxylase monoclonal antibody (Product # MA1-24654). Immunoperoxidase (A and C) and immunofluorescent (B, D–H) labeling of intrinsic cardiac adrenergic (ICA) cells in human hearts are shown. ICA cells expressing tyrosine hydroxylase (TH) immunoreactivity (red) are distributed diffusely throughout the left ventricular (LV) myocardium. Perivascular location is a frequent feature of ICA cells. C, arrow: terminal arteriole. E: abundant ICA cells in the smooth muscle layers of epicardial circumflex coronary artery. TH-expressing sympathetic nerve fibers (D and G, arrows) can occasionally be seen in the field. B and D, insets: magnified ICA cell images (arrows). TH immunoreactivity (green) was identified in ICA cells and sympathetic nerve fibers in the sinoatrial nodal tissue (G). ICA cells are seen in transplanted human LV tissue (H). Scale bars = 10 µm, except in B (20 µm).

MA1-24654 detects Tyrosine Hydroxylase from human, mouse, and rat samples.
MA1-24654 has been successfully used in Western blot, ICC/IF, and immunohistochemistry (frozen sections) procedures.
The MA1-24654 immunogen is recombinant protein corresponding to the C-terminal portion of mouse Tyrosine Hydroxylase.
Tyrosine hydroxylase (TH) is the rate-limiting enzyme in the synthesis of the catecholamine neurotransmitters (dopamine, epinephrine, and norepinephrine). It is responsible for the conversion of L-tyrosine to L-dopa in the catecholamine synthesis pathway. In all species, catecholamine synthesis is regulated by the interaction of TH with a cofactor, tetrahydrobiopterin (BH4). BH4 binds to the TH catalytic domain, resulting in enzymatic activity. Unlike TH in non-primate species, four human TH mRNA splice variants (hTH1-hTH4) have been isolated. These variants are identical in their catalytic domain, but differ in their N-terminal, regulatory domains. Little information has been uncovered regarding the regulatory role of these isoforms in vivo.
The role of TH in the synthesis of catecholamine neurotransmitters suggests a correlation between the enzyme and a number of neuropathogenic diseases characterized by irregular catecholamine levels. Catecholamine level irregularities have been uncovered in Parkinson's disease, schizophrenia, and dystonia, as well as a variety of cardiovascular diseases.
