PG - 45-9 AB - Recombinant nucleocapsid (rN) protein N of porcine reproductive and respiratory syndrome virus (PRRSV) was prepared, by using the E. coli expressiom system. Insertion of a polyhistidine marker into the structure of the protein allowed the latter to be purified by metal-chelate affinity chromatography. The purity of protein was confirmed by PAAG electrophoresis and its immunospecificity was verified by immunoblotting using rN-specific monoclonal antibodies. The protein was used as an antigen to develop indirect ELISA of PRRSV antibodies. ELISA was shown to be highly sensitive and specific.
