Abstract: A monoclonal antibody binding selectively to neurosin obtained from hybridomas, in particular, strain 2B2-6 and strain S2E5 showing stable proliferation ability. These hydridomas are obtained by fusing mouse spleen cells having a high antibody titer against neurosin with mouse-derived myeloma cells, screening fused cells being highly reactive with neurosin, and thus producing an antibody binding specifically to neurosin. By using this antibody, various diseases in which neurosin participates can be diagnosed.
