Abstract：
:Monoclonal antibody N210 (mabN210) recognizes the 210 kdalton neurofilament protein in mammals and gives characteristic immunocytochemical staining of neurofilament-rich processes. For example, in the cerebellum it recognizes myelinated axons and the calyx formed by basket cell axon collaterals. The distribution of mabN210 immunoreactivity was studied in the gymnotid brain (Apteronotus albifrons). In contrast to the mammalian distribution, mabN210 immunoreactivity was not found in most axons of the gymnotid brain. Instead, deposits of reaction product were present in the somata and dendrites of most neurons and were especially dense in those neurons with extensive dendritic trees, the Purkinje cells, pyramidal cells of the electrosensory lateral line lobe, the crest cells of the nucleus medialis and the pyramidal cells of the tectum. Electrosensory lateral line lobe pyramidal cells are known to contain few, if any, neurofilaments in their dendrites. Western blots of whole gymnotid brain proteins demonstrated that mabN210 recognizes two polypeptides apparent molecular weights 60 and 19 kdaltons. These proteins are thus antigenically similar to neurofilament protein and their expression in the gymnotid brain may be related to the peculiar dendritic branching pattern of Purkinje cells and similar cell types.
