Tyrosine hydroxylase (TH) is the rate-limiting enzyme in the synthesis of the catecholamines dopamine, epinephrine and norepinephrine. Therefore the regulation of the TH enzyme represents the central means for controlling the synthesis of these important catecholamines. TH has a large molecular diversity, resulting from differential splicing of its mRNA, which is tissue specific and might result in long term changes in activity of the enzyme and the availability of neurotransmitter at various synapses. The presence of different DNA sequences at the TH locus confers susceptibility to various disorders of the brain including manic-depression and schizophrenia. Parkinson's disease is also considered a TH deficiency, as low dopamine levels are a consistent neurochemical abnormality. Applications: Suitable for use in Immunofluorescence, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Cellular Localization: can be used as a marker for dopaminergic and noradrenergic neurons. Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 3 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
