Abstract: The specific monoclonal antibody against avian adenovirus type 4 (FADV-4) Fiber2 protein was prepared. The FADV-4 Fiber2 protein was purified and immunized BALB/C mice as an immunogen. Lymphocytes were isolated from spleen and fused with mouse myeloma cells SP2/0. Ten hybridoma cell lines including 1B5F1, 1B5G11, 1B5C1, 1B5D2, 1B5E3, 1B5F3, 1B5E4, 1B5G4, 1B5A8 and 1B5G8 were screened for stable secretion of monoclonal antibody against FADV-4 Fiber2 protein. Ascites were prepared from 1B5F1 cell line with the highest antibody secretion level, and the specificity was detected by Dot blot and indirect immunofluorescence assay (IFA). The results showed that 10 hybridoma cell lines were successfully prepared. The ascites could react specifically with FADV-4 Fiber2 protein and fADV-4 challenged chicken liver tissue, which proved that the specific monoclonal antibody of FADV-4 Fiber2 protein was successfully prepared.
