to begin examining retrograde transport in a single invertebrate neuron we have used wheat germ agglutinin conjugated to horseradish peroxidase ( wga-hrp ) , 18 h after the conjugate was injected extracellularly into the neuropil of the buccal ganglion of aplysia , hrp reaction product could be detected cytochemically in putative lysosomes , cisternae and vesicles near golgi in the giant metacerebral neuron ( gcn ) of the cerebral ganglion .
