Prokaryotic expression of f protein from PPRV and characterization of its polyclonal antibody

Monoclon Antib Immunodiagn Immunother. 2013 Feb;32(1):26-31. doi: 10.1089/mab.2012.0063.

Abstract

The goal of this study was to evaluate the specificity of a polyclonal antibody against the F protein from Peste des petits ruminants virus (PPRV). A pET30a/F prokaryotic expression vector was successfully constructed and its recombinant protein was expressed. The result of Western blot analysis showed that the fusion protein pET30a/F possessed good immunoreactivity and the purified recombinant protein was then used as the antigen to raise anti-pET30a/F polyclonal antibody in rabbits. The polyclonal antibody titer against the recombinant F protein was confirmed by indirect ELISA, and the protein's specificity against pET30/F polyclonal antibody was confirmed by both Western blot and indirect immunofluorescence assay in transfected cells. In short, we obtained the high-level expression of recombinant F protein as well as high titers of rabbit polyclonal antibody specificity against F protein in pCAGGS/F transfected cells. This special polyclonal antibody offers a valuable and useful tool for further study of the pathogenesis of PPRV early infection and the structural and functional characterization of PPRV F protein.
