[Preparation and identification of monoclonal antibodies against African horse sickness virus VP7].

Objective To prepare the monoclonal antibody (mAb) against the African horsefever virus (AHSV) VP7 protein and to identify it. Methods mAbs were prepared by using baculovirus expressed VP7 protein in BALB/c mice, and the effect of mAb was detected by ELISA, indirect immunofluorescence assay (IFA), and AHSV positive serum blockade. Results Four mAb strains were selected, including 20A8, 28B3, 30G8 and 47E6, among which 47E6 had the best blocking effect. Conclusion mAbs were successfully prepared against VP7 protein.
