title: Retrograde transport of bisbenzimide and propidium iodide through axons to their parent cell bodies.
abstract: Two fluorescent substances bisbenzimide (Bb), which fluoresces yellow-green and propidium iodide (PI), which fluoresces orange were found to be transported retrogradely through axons to their parent cell bodies in rat and cat. Bb gives a very strong and long lasting fluorescent retrograde neuronal labeling and is very effectively transported over long distances both in rat and cat. Bb and PI also label glial nuclei around retrogradely labeled neurons. Bb in addition labels glial nuclei along axons through which it is transported. Bb and PI can be transported retrogradely through two divergent collaterals to one and the same cell.
