1/100 - 1/1000. Perform heat mediated antigen retrieval using 10mM Citrate buffer (pH6.0) or Tris-EDTA buffer (pH8.0) before commencing with IHC staining protocol.
Plays an important role in the physiology of adrenergic neurons.
Mainly expressed in the brain and adrenal glands.
Catecholamine biosynthesis; dopamine biosynthesis; dopamine from L-tyrosine: step 1/2.
Defects in TH are the cause of dystonia DOPA-responsive autosomal recessive (ARDRD) [MIM:605407]; also known as autosomal recessive Segawa syndrome. ARDRD is a form of DOPA-responsive dystonia presenting in infancy or early childhood. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures. Some cases of ARDRD present with parkinsonian symptoms in infancy. Unlike all other forms of dystonia, it is an eminently treatable condition, due to a favorable response to L-DOPA. Note=May play a role in the pathogenesis of Parkinson disease (PD). A genome-wide copy number variation analysis has identified a 34 kilobase deletion over the TH gene in a PD patient but not in any controls.
Belongs to the biopterin-dependent aromatic amino acid hydroxylase family.
Immunofluorescent analysis of methanol-fixed SK-N-SH cells labelling Tyrosine Hydroxylase with ab137721 at 1/500 dilution (left panel) and co-stained with Hoechst 33343 (right panel).
SK-N-SH cells were fixed in -20°C 100% MeOH for 5 min.
