title: Immunocytochemical localization of acetylcholine receptors in locust brain using auto-anti-idiotypic acetylcholine antibodies.
abstract: Auto-anti-idiotypic antibodies have been detected in antisera of rabbits immunized with an acetylcholine (ACh) conjugate. These antibodies were found to bind to ACh receptor (ACh-R) purified from different species membranes. They competed with the ACh-R antagonist alpha-bungarotoxin and some agonists such as ACh conjugate and ACh itself. They did not recognize acetylcholinesterase. Their characterization 'in vitro' suggested their employment as an immunohistological marker for ACh-R. In the locust brain, specific immunoreactivity was found in neuropils of the protocerebrum, the optic lobes, the deutocerebrum and the tritocerebrum.
