      Alternate Names
      • Tryptophan 5-monooxygenase 1
      • indoleacetic acid-5-hydroxylase
      • tryptophan 5-hydroxylase

      • tryptophan hydroxylase 1
      Background InformationTryptophan hydroxylase (TPH) is an enzyme involved in the synthesis of the neurotransmitter serotonin. It is responsible for addition of the -OH group (hydroxylation) to the 5 position to form the amino acid 5-hydroxytryptophan (5-HTP), which is the initial and rate-limiting step in the synthesis of the hormone serotonin. It is also the first enzyme in the synthesis of melatonin.

      PresentationPurified sheep polyclonal liquid in 150 mM NaCl, 10 mM HEPES (pH 7.5), 100 μg/mL BSA and 50% glycerol.
      ApplicationDetect Tryptophan Hydroxylase using this Anti-Tryptophan Hydroxylase Antibody validated for use in IH & WB.
      Key Applications
      • Immunohistochemistry
      • Western Blotting
      Application NotesImmunohistochemistry(peroxidase):
      Performed on formaldehyde fixed tissue of a previous lot. Useful for cell body but not fiber staining.

      Optimal working dilutions must be determined by the end user.
      Biological Information
      ImmunogenRecombinant rabbit tryptophan hydroxylase, isolated as inclusion bodies from E. coli and purified by preparative SDS-PAGE.
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityRecognizes Tryptophan Hydroxylase. Reacts with human and rat brain tissues by immunoblotting and immunohistochemistry. Based on the relatively high degree of homology of tryptophan hydroxylase, the antibody should cross-react with other mammalian species. Recently studies have indicated that AB1541 can cross react with Tyrosine hydroxylase on western blots, weakly. Cross reactivity in the native state is untested.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the pterin-dependent aromatic acid hydroxylase family. The encoded protein catalyzes the first and rate limiting step in the biosynthesis of serotonin, an important hormone and neurotransmitter. The human genome contains two related tryptophan hydroxylases, one on chromosome 11p15-p14 and one on chromosome 12q21. This gene is expressed predominantly in the gut, pineal gland, spleen, and thymus.

      Usage Statement
      • 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.
      Storage and Shipping Information
      Storage ConditionsStable for 6 months at -20ºC to -80ºC in undiluted aliquots from date of receipt.
      Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol-containing solutions to become frozen during storage.
