Tyrosine hydroxylase (also know as Tyrosine 3-hydroxylase and Tyrosine 3-monooxygenase) 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.
It is expected that the antibody will react with most mammalian and many non-mammalian species. It has been reported that this antibody does not work on paraffin embedded human tissue.
Tyrosine hydroxylase. By western blot, AB152 selective labels a single band at approximately 62kDa (reduced) corresponding to Tyrosine Hydroxylase. It is expected that the antibody will react with most mammalian and many non-mammalian species. It has been reported that this antibody does not work on paraffin embedded human tissue.
