Development of competitive ELISA for serodiagnosis on African horsesickness virus using baculovirus expressed VP7 and monoclonal antibody
2003
VP7, the sero-group common antigen, of African horsesickness virus (AHSV-4) was expressed in insect cells by recombinant baculovirus. To develop a specific diagnostic method, monoclonal antibody (Mab) against VP7 was prepared and investigated as diagnostic reagent with the baculovirus expressed VP7. However, the Mab against VP7 of AHSV cross-reacted with Chuzan virus by the indirect immunofluorescence assay (IFA), confirming the presence of conserved domain of VP7 among Orbiviruses. This study describes two types of ELISA; Mab linked indirect (I-ELISA) and competitive-ELISA (C-ELISA) using baculovirus expressed VP7 as an antigen. These ELISAs were compared for serodiagnosis of AHSV showing that C-ELISA was more specific than I-ELISA. The results indicated that C-ELISA is applicable to serodiagnosis of AHSV regardless of serotypes.
