• Product name
  • Description
    Rabbit polyclonal to Nociceptin
  • Host species
  • Specificity
    Achieved by producing antibody only against the C terminal portion of the full peptide that avoids possible cross-reaction with enkephalin, dynorphin and endorphin. Specificity was tested by the use of various peptides for adsorption in immunohistochemistry including enkephalin, dynorphin and endorphin.
  • Tested applications
    Suitable for: ELISA, IHC-Fr, RIAmore details
  • Species reactivity
    Reacts with: Rat, Guinea pig
  • Immunogen

    Synthetic peptide CTGARKSARKLANQ corresponds to rat nociceptin protein with a cysteine added at the N terminal for conjugation to diphtheria toxoid. The peptide was cross-linked by maleimidocaproyl-N-hydroxy succinimide.

  • General notes
    This antibody can be used for staining nerve fibres in guinea pig myenteric plexus. Staining was established with the use of fluorescence immunohistochemistry (CY3).



Our Abpromise guarantee covers the use of ab6174 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Function
    Nociceptin: Ligand of the opioid receptor-like receptor OPRL1. It may act as a transmitter in the brain by modulating nociceptive and locomotor behavior. May be involved in neuronal differentiation and development.
    Nocistatin: Blocks nociceptin action in pain transmission by inhibiting nociceptin-induced hyperalgesia and allodynia.
    Orphanin FQ2: Has potent analgesic activity.
  • Tissue specificity
    Predominantly expressed in the brain and spinal cord. Also expressed and secreted by peripheral blood neutrophils following degranulation.
  • Sequence similarities
    Belongs to the opioid neuropeptide precursor family.
  • Post-translational
    Specific enzymatic cleavages at paired basic residues probably yield other active peptides besides nociceptin.
    The N-terminal domain contains 6 conserved cysteines thought to be involved in disulfide bonding and/or processing.

Thank you for your enquiry. "17aa" refers to 17 amino acids. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

We use an estimate for anti-sera since there is no routine technique available for measuring the fraction of specific IgG to your target. The amount of IgG in whole anti-sera is around 10mg/ml and the amount of specific IgG is normally around 5-10% so ...
