Antibody to tyrosine hydroxylase (TH) - the rate limiting enzyme in catecholamine synthesis and used as a marker for catecholaminergic (dopaminergic and noradrenergic) neurones in the CNS. Part of the ValidAb™ range of highly validated, data-rich antibodies.
Midbrain dopaminergic neurones stained for tyrosine hydroxylase with HB6589. Method: Rat brains were dissected and fixed overnight in 4% PFA before then being incubated in 30% sucrose (in PBS) until sunk (approx. 48hrs). A freezing microtome was used to cut 40µm horizontal slices before sections were incubated in 1% NaBH4 for 15 minutes. Sections were blocked in 0.05M glycine, 2% BSA and 3% goat serum before incubation overnight in HB6589 (1:1000 dilution). This was followed by a two-hour incubation with secondary antibody at a 1:300 dilution (polyclonal donkey anti-chicken DyLight 488, Thermofisher, A78948). DAPI (HB0747) was used at 1µg/ml to visualise cell nuclei and sections were mounted using MightyMount Antifade Fluorescence Mounting Medium (hardset). For more detail please see our IHC(IF) protocol. Images were captured using a Leica DMI6000B inverted epifluorescence microscope. The image was captured using a 100x objective in a z-stack (0.22µm spacing). The image was captured as a tilescan using A4 (72ms @1x gain exposure) and GFP (70ms @ 1x gain exposure) filters. The stack was deconvolved using Huygens professional then flattened using a maximum Z projection in ImageJ (Schindelin et al., 2012. Nat Methods, 9(7), 676–682).

Images were captured using a Leica DMI6000B inverted epifluorescence microscope. The image was captured using a 40x objective in a z-stack (0.55µm spacing). The image was captured as a tilescan using DAP (16ms exposure), L5 (76ms exposure), TX2 (15ms exposure) and Y5 (281ms exposure) filters. The stack was deconvolved using Huygens professional then flattened using a maximum Z projection in ImageJ (Schindelin et al., 2012. Nat Methods, 9(7), 676–682).

Positive control
Tissue known to have a high expression of catecholaminergic neurones (e.g. striatum or substantia nigra). PC-3 and SK-BR-3 cell lines also show tyrosine hydroxylase expression.
Negative control
Areas of the brain with low expression of catecholaminergic neurones (e.g. cortex). Most cells lines do not express TH (e.g. HEK293, HeLa, SH-SY5Y).
Tyrosine hydroxylase has 6 isoforms produced by alternative splicing:
Isoform 3 / TH type 4 (canonical) - 528aa, 58.6kDa.
Isoform 1 / TH type 3 - 524aa, 58.1kda,
Isoform 2 / TH type 1/HTH-1 - 497aa, 55,6kDa,
Isoform 4 / TH type 2/hTH-Delta2 - 501aa, 56.0kda,
Isoform 5 / hTH-Delta,2,8,9 - 407aa, 45.3kDa,
Isoform 6 / hTH-Delta1b,2,8,9 - 403aa 44.9kDa
Expression
Mainly expressed in the dopaminergic, noradrenergic and other catecholingergic neurones in the brain and adrenal glands. There is also lower peripheral expression in a variety of tissues.
Subcellular expression
Expression is enriched in axon terminals alongside cytosolic and perinuclear expression.
Processing
None
Post translational modifications
Subject to phosphorlyation on Ser19, Ser62, Ser71 and Ser502.
Homology (compared to human)
Mouse and rat show 82.8% and 83.7% identity to human tyrosine hydroxylase respectively in a BLAST search.
Similar proteins
The following proteins were identified as being similar in a BLAST search:
Phenylalanine-4-hydroxylase – 52.8% identity
Tryptophan-5-hydroxylase 1 – 50.1% identity
Tryptophan-5-hydroxylase 2 – 52.1% identity
Storage & Handling
Storage instructions
-20°C
Reconstitution advice
We recommend reconstituting with either:
dH2O and storing at 4°C
50:50 ratio of dH2O to glycerol and storing at -20°C
dH2O then aliquot and store at -80°C
Take care when opening as the precipitate is extremely light and can easily be lost if disturbed. When reconstituting make sure that the antibody is thoroughly dissolved by pipetting up and down before giving the antibody a brief spin at <10,000g to make sure that all material is recovered and at the bottom of the tube.
