Production of Monoclonal Antibody against Prokaryotically Expressed G1 Protein of Bovine Ephemeral Fever Virus
Authors
Abstract:
Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this study was to produce a monoclonal antibody (MAb) against recombinant G1 antigen expressed into Escherichia coli. For this purpose, somatic cell hybrids between SP2/0 myeloma cells and spleen cells derived from Balb/c mice immunized with maltose-binding protein (MBP)-G1 fusion protein were established. After three rounds of cloning, the stability of antibody secretion in the positive clones was confirmed by ELISA and the reactivity of the MAbs against recombinant G1 was verified by Western blot analysis. The specific MAbs produced against recombinant G1 antigen in this study could be used for establishing BEFV diagnostic experiments in the future.

Bovine Viral Diarrhea virus (BVDV) is an important viral pathogen of cattle causing several clinical syndromes. There are usually no pathognomonic clinical signs of BVDV infection. Diagnostic investigations therefore rely on serological detection and virus isolation. Nonstructural protein 3 (NS3) as immunogenic protein of BVDV is genetically and antigenically conserved among different isolates....

Bovine ephemeral fever is an acute and arthropod-borne viral disease of cattle and water buffalo which occurs seasonally in most of the world tropical and subtropical regions. The epizootic feature of the disease has been reported in Iran with serious economic consequences. The surface glycoprotein G of bovine ephemeral fever virus (BEFV) is composed of 4 antigenic sites (G1-G4) and plays the m...

BACKGROUND The bovine ephemeral fever virus (BEFV) glycoprotein neutralization site 1 (also referred as G1 protein), is a critical protein responsible for virus infectivity and eliciting immune-protection, however, binding peptides of BEFV G1 protein are still unclear. Thus, the aim of the present study was to screen specific polypeptides, which bind BEFV G1 protein with high-affinity and inhib...
