OBJECTIVE: To prepare monoclonal antibodies against a newly discovered and conserved linear epitope of Rabies virus nucleoprotein and to use them in a rabies diagnostic test.
METHODS: Synthetic peptide containing the epitope was used as immunogen to prepare hybridoma cell lines by classical hybridoma technology. Anti-peptide monoclonal antibodies produced in ascites of inoculated Balb/c mice were labeled with fluorescein isothiocyanate (FITC) after purification and used in fluorescent antibody test (FAT).
RESULTS: Two positive hybridoma cell lines, RVNP-mAb1-CL and RVNP-mAb2-CL, were obtained. RVNP- mAb1-CL produced a higher concentration of monoclonal antibody RVNP-mAb1 in Balb/c ascites. FITC-labeled RVNP-mAb1 showed correct results on certain Rabies virus-positive canine brain tissue samples and cells of a small subclone of baby hamster kidney 21 cell line (BSR).
CONCLUSION: FITC-labeled RVNP-mAb1 has potential application for laboratory diagnosis of rabies.
