Description_x000D_ General description_x000D_ Anti-Tyrosine Hydroxylase antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the hybridoma TH-2 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with purified rat Tyrosine Hydroxylase. Tyrosine Hydroxylase (TH) also known as tyrosine 3- monooxygenase, is encoded by the gene mapped to human chromosome 11p15.5. It is a tetrameric enzyme composed of four subunits. Four TH Isoforms were identified in humans._x000D_ Immunogen_x000D_ purified rat Tyrosine Hydroxylase_x000D_ Application_x000D_ Anti-Tyrosine Hydroxylase antibody, Mouse monoclonal has been used in various immunochemical techniques including immunoblotting, immunohistochemistry, immunofluorescence and immunoprecipitation._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Tyrosine Hydroxylase (TH) catalyzes the hydroxylation of L-tyrosine to L-3,4-dihydroxyphenylalanine (L-dopa) in brain and adrenal medulla which is the initial and rate limiting step of the neurotransmitters and hormones catecholamines (dopamine, norepinephrine and epinephrine) biosynthesis. Therefore, TH plays a key role in the physiology of adrenergic neurons. Tyrosine Hydroxylase (TH) deficiency is associated with the development of wide variety of phenotypic spectrum such as several types of dystonia, early-onset of Parkinson′s, cerebral palsy or spastic paraplegia and both primary and secondary deficiencies of cerebrospinal fluid (CSF) neurotransmitter metabolites.
