Phospho-Ser40 Tyrosine Hydroxylase Antibody

Affinity purified rabbit polyclonal antibody

  • WB - Phospho-Ser40 Tyrosine Hydroxylase Antibody AN1119
    Western blot of recombinant phospho- and dephospho-TH showing selective immunolabeling by the phospho-specific antibody of the ~60k TH phosphorylated at Ser40. The pan-specific antibody (anti-pan-TH) recognized both the phospho- and dephospho-TH while most importantly, the phospho-specific antibody(anti-ser40 TH),recognized only phospho-TH.
  • IHC - Phospho-Ser40 Tyrosine Hydroxylase Antibody AN1119
    Immunohistochemical staining of retina with the pan-tyrosine hydroxylase (pan-TH) and phospho-specific tyrosine hydroxylase (phospho-TH) antibodies. The pan-TH antibody shows extensive labeling in this photomicrograph of the retina. In contrast, the phospho-TH antibody selectively labels only the two amacrine cells in this light-stimulated retina example.

Additional Information
Gene ID 25085
Gene Name TH
Other Names Tyrosine 3-monooxygenase, Tyrosine 3-hydroxylase, TH, Th
Target/Specificity Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser40 conjugated to KLH.
Dilution WB~~ 1:1000
IHC~~ 1:1000
Format Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.
Antibody Specificity Specific for the ~60k tyrosine hydroxylase protein phosphorylated at Ser40. Some higher molecular weight bands may be detected by the antibody depending upon the brain region being studied, protein loads and the detection methods used. The antibody has three orders of magnitude selectivity over dephospho TH.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsPhospho-Ser40 Tyrosine Hydroxylase Antibody is for research use only and not for use in diagnostic or therapeutic procedures.

Tyrosine hydroxylase (TH) is the rate-limiting enzyme in the synthesis of the catecholamines Dopamine and Norepinephrine. TH antibodies can therefore be used as markers for dopaminergic and noradrenergic neurons in a variety of applications including depression, schizophrenia, Parkinson’s disease and drug abuse (Kish et al., 2001; Zhu et al., 2000; Zhu et al., 1999). TH antibodies can also be used to explore basic mechanisms of dopamine and norepinephrine signaling (Witkovsky et al., 2000; Salvatore et al., 2001; Dunkley et al., 2004). The activity of TH is also regulated by phosphorylation (Haycock et al., 1982; Haycock et al., 1992; Jedynak et al., 2002). Phospho-specific antibodies for the phosphorylation sites on TH can be used to great effect in studying this regulation and in identifying the cells in which TH phosphorylation occurs.
