Extra-synaptic localization of alpha-bungarotoxin receptors in cultured chick ciliary ganglion neurons.
Surface [125I]alpha-bungarotoxin receptors were localized on dissociated cultures of embryonic chick ciliary ganglion neurons by electron microscopic autoradiography. Grain density was 4-5-fold higher on cell body membrane versus neuritic process membrane, and there was no apparent concentration of grains at morphologically identifiable inter-neuronal synapses.
