  • Relevance

    Beta-endorphin is an endogenous opioid peptide neurotransmitter found in the neurons of both the central and peripheral nervous system. ß-endorphin is a peptide, 31 amino acids long, resulting from processing of the precursor pro-opiomelanocortin (POMC). ß-endorphin is found in neurons of the hypothalamus as well as the pituitary gland. It is an agonist of the opioid receptors, with evidence suggesting that it serves as the endogenous ligand of the µ-opioid receptor, the same receptor to which the chemicals extracted from opium, such as morphine and codeine, have their analgesic and addictive effects

Thank you for your question about our beta Endorphin antibody, ab54205. We have the same clone, B31.15, listed under a different product identifier, ab1419. The title of a reference listed on the datasheet of that product suggests that the clone will recognize POMC, but I have not confirmed. beta Endorphin antibody [B31.15] (ab1419) Click here (or use the following: https://www.abcam.com/index.html?datasheet=1419). Detection of mRNA transcripts of truncated opiate precursor (POMC) in human cartilage. Andjelkov N et al. Cell Biochem Funct. 2006 May-Jun;24(3):229-35. http://www.ncbi.nlm.nih.gov/pubmed/15898126?dopt=Abstract The antibody is raised against beta endorphin, but it is not clear if the epitope that it recognizes is unique to beta enodrphin, or is also present on POMC. I hope the reference is useful. If you have any questions, please contact us.
