Abstract

The rabies virus is a neurotropic virus that causes fatal disease in humans and animals. However, not all commercial antibodies against rabies virus (RABV) structural proteins are generally available, and production of high-quality monoclonal antibodies (MAbs) requires high purification of virus particles and special facilities and is time-consuming. By using RABV-infected suckling mouse brain as antigens in this study, 11 hybridoma cells secreting MAbs against RABV were obtained, which showed strong reactivity with RABV-infected Vero cells in immunofluorescence assay. Among the 11 MAbs, three MAbs (1B11, 1C8, and 8H12) showed a neutralizing effect to RABV, while MAb 4B7 recognized the recombinant nucleoprotein (N) of RABV expressed in Vero cells; seven MAbs (1H3, 3H7, 4E7, 4G3, 5A10, 6C9, and 7B3) reacted specifically with phosphoprotein (P) of RABV. The MAbs developed in this study will be useful in establishing a diagnostic test and study on the interactions between RABV and its host.
