Antigenic Structure of the Nucleocapsid Protein of Porcine Reproductive and Respiratory Syndrome Virus
A collection of 12 monoclonal antibodies (MAbs) raised against porcine reproductive and respiratory syndrome (PRRS) virus was used to study the antigenic structure of the virus nucleocapsid protein (N). The full-length N gene, encoded by open reading frame 7, was cloned from the Canadian PRRS virus, PA-8. Deletions were introduced into the N gene to produce a series of nine overlapping protein ...
متن کاملEpitope mapping of the nucleocapsid protein of European and North American isolates of porcine reproductive and respiratory syndrome virus.
Two major genotypes of porcine reproductive and respiratory syndrome virus (PRRSV) have been described, which correspond to the European and North American isolates. PRRSV nucleocapsid (N) protein has been identified as the most immunodominant viral protein. The N genes from two PRRSV isolates, Olot/91 (European) and Québec 807/94 (North American), were cloned and expressed in: (i) baculovirus ...
متن کاملIdentification of a conserved epitope cluster in the N protein of porcine reproductive and respiratory syndrome virus.
In this study, 4 overlapping fragments and 12 overlapping peptides of the nucleocapsid (N) protein from porcine reproductive and respiratory syndrome virus (PRRSV) were expressed as glutathione S-transferase (GST) fusion proteins and used to probe a panel of 16 anti-N protein monoclonal antibodies (mAbs) by ELISA. The minimal epitope sequence of the following seven mAbs was determined by sequen...
متن کاملStructure of the nucleocapsid protein of porcine reproductive and respiratory syndrome virus.
Porcine reproductive and respiratory syndrome virus (PRRSV) is an enveloped RNA virus of the Arteriviridae family, genomically related to the coronaviruses. PRRSV is the causative agent of both severe and persistent respiratory disease and reproductive failure in pigs worldwide. The PRRSV virion contains a core made of the 123 amino acid nucleocapsid (N) protein, a product of the ORF7 gene. We ...
متن کاملAntigenic variability among North American and European strains of porcine reproductive and respiratory syndrome virus as defined by monoclonal antibodies to the matrix protein.
Two hybridoma cell lines producing monoclonal antibodies (Mabs) to the 19-kDa matrix (M) protein of porcine reproductive and respiratory syndrome virus (PRRSV) were obtained from BALB/c mice that were immunized with a reference Quebec tissue culture-adapted strain (strain IAF-Klop). The polypeptide specificities of the MAbs were determined by immunoblotting and immunoprecipitation tests with co...
