Identification of synaptic acetylcholine receptor sites in retina with peroxidase-labeled α-bungarotoxin

PMCID: PMC431525  PMID: 269390

Abstract

An α-bungarotoxin-horseradish peroxidase conjugate, which binds specificity to nicotinic acetylcholine receptors, was synthesized. This conjugate was bound by 5-7% of the synapses in the inner plexiform layer of the chicken retina. Bipolar ribbon synapses as well as amacrine synapses bound the conjugate.

Keywords: neurotransmitter, central nervous system, nerve cell membrane, histochemistry, electron microscopy
