[Selective staining by procion dyes of olfactory sensory neurons in the catfish Ictalurus nebulosus (author's transl)].
Procion Brilliant Yellow M4RAN and Procion Yellow M4R applied to the catfish olfactory mucosa stain intravitally and enter the olfactory receptors by their dendrites. The dye invades the receptor pericaryon and subsequently migrates within the axon in distal direction. Fluorescence microscopy of aldehyd fixed and paraffin sectioned preparations reveals clear selective staining of the sensory neurons in yellow colour.
