A single reactive amino group at the extended carboxyl terminus permits various reporter groups to be attached, such as 125I-labeled Bolton-Hunter reagent, fluorescein isothiocyanate, or biotin. These derivatives have high affinity and selectivity for the dynorphin (kappa opioid) receptor. An incidental finding is that untreated guinea pig brain membranes have saturable avidin binding sites.<\/jats:p>","DOI":"10.1073\/pnas.85.19.7375","type":"journal-article","created":{"date-parts":[[2006,5,31]],"date-time":"2006-05-31T06:43:52Z","timestamp":1149057832000},"page":"7375-7379","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":19,"title":["\"DAKLI\": a multipurpose ligand with high affinity and selectivity for dynorphin (kappa opioid) binding sites."],"prefix":"10.1073","volume":"85","author":[{"given":"A","family":"Goldstein","sequence":"first","affiliation":[{"name":"Department of Pharmacology, Stanford University, CA 94305."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr","given":"J J","family":"Nestor","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Stanford University, CA 94305."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Naidu","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Stanford University, CA 94305."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S R","family":"Newman","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Stanford University, CA 94305."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[1988,10]]},"container-title":["Proceedings of the National Academy of Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pnas.org\/doi\/pdf\/10.1073\/pnas.85.19.7375","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,13]],"date-time":"2022-04-13T12:48:19Z","timestamp":1649854099000},"score":1,"resource":{"primary":{"URL":"https:\/\/pnas.org\/doi\/full\/10.1073\/pnas.85.19.7375"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1988,10]]},"references-count":0,"journal-issue":{"issue":"19","published-print":{"date-parts":[[1988,10]]}},"alternative-id":["10.1073\/pnas.85.19.7375"],"URL":"https:\/\/doi.org\/10.1073\/pnas.85.19.7375","relation":{},"ISSN":["0027-8424","1091-6490"],"issn-type":[{"value":"0027-8424","type":"print"},{"value":"1091-6490","type":"electronic"}],"subject":[],"published":{"date-parts":[[1988,10]]},"assertion":[{"value":"1988-10-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
