The tachykinins belong to an evolutionary conserved family of peptide neurotransmitters that share the c-terminal sequence Phe-X-Gly-Leu-Met-NH2 and have an established role in neurotransmission. The mammalian tachykinins include substance P, neurokinin A (NKA) and neurokinin B (NKB) which exert their effects by binding to specific receptors. Tachykinin peptides are important in the mediation of many physiological and pathological processes including inflammation, pain, migraine headache and allergy induced asthma. Three tachykinin receptor types have been characterized, NK-1, NK-2 and NK-3 which have preferential affinities for SP, NKA and NKB respectively. All three receptors share a high degree of sequence homology, have seven transmembrane spanning domains and similar signal transduction mechanisms (e.g. G-protein coupled activation of phospholipase C).

FAQs for NK1R Antibody (NB300-119). (Showing 1 - 4 of 4 FAQs).

  1. What amino acid residues are recognized by the anti- Neurokinin 1 Receptor antibody NB300-119?
    • The exact immunogen sequence is deemed proprietary by the lab, and we have not epitope mapped this particular antibody. Therefore we do not know exactly where NB300-119 binds to its target. However, the immunogen was derived from the N-terminus of the human Neurokinin 1 Receptor protein. If there is a specific region that you are interested in targeting, or excluding, please send your desired sequence information to our Technical Support team at technical@novusbio.com, for comparison to the immunogen sequence used to synthesize the antibody.
  2. Our customer would like to know the MW that this antibody can detect in western blot.
    • The MW of this protein is 46KDa.
  3. One of our customers is willing to purchase this antibody, before placing the order she would like to know if it can be used for formalin-fix, paraffin-embedded sections in immunohistochemistry?
    • Yes, this product has been validated for use in IHC paraffin embedded sections.
  4. I have been trying this antibody for Western blot incortex and spinal cord from rat without results. Is there any reference where they have done WB with this antibody?
    • At this time we do not have any references found where this has been described in WB, and of the references we have they are all for use in staining applications. We do have a product review however from a customer who observed positive results in WB as well as our own QC testing data that show positive staining in brain samples. This link (Product Specific Protocol) is also the recommended protocol for this one that may be helpful to you. If you have any difficulties with this one we would be happy to have the lab take a look at your results and compare them to our QC tests.
