Identification of synaptic acetylcholine receptor sites in retina with peroxidase-labeled alpha-bungarotoxin
Abstract
An alpha-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.
