Technical Data
Tyrosine Hydroxylase (TH, TYH, Tyrosine 3 Hydroxylase, Tyrosine 3 Monooxygenase)
Tyrosine hydroxylase (TH) plays an important role in the physiology of adrenergic neurons. It is the first and rate-limiting enzyme involved in the biosynthesis of the catecholamines Dopamine and Norepinephrine from tyrosine. TH is, therefore, a useful marker for dopaminergic and noradrenergic neurons. The enzymatic activity of TH requires ferrous ions as cofactors and is believed to be regulated by phosphorylation. At least four isoforms of human TH have been identified which result from alternative splicing.

Suitable for use in Western Blot, ELISA, Immunohistochemistry, Immunofluorescence and Immunoprecipitation. Other applications have not been tested.

Recommended Dilutions:
Western Bot: 1:1000 on 10ug of PC12 lysates.
Immunohistochemistry: 1:100-1:1000 at 4C, 1-3 days. Stains both fresh frozen and paraffin embedded tissue samples by indirect immunofluorescence and immunoperoxidase. Reported not suitable for use on paraffin embedded, human tissue.
Immunofluorescence: 1:100-1:1000; Fixed with 4% PFA overnight at 4C.
Optimal dilutions to be determined by the researcher.
