Monoclonal antibodies against proteins of the IBR virus nucleocapside and their assessing by ELISA
Monoclonal antibodies were produced against the nucleocapside of a field IBR virus strain. The virus was growth in MOBK cell line. Viral components were purified and concentrated in a continuous 30% sacarose gradient followed by chemical precipitation. Nucleocapsides were run in a 10% SDS-PAGE gel. Positive hybridomes were tested using a direct ELISA developed in our laboratory. As a result eigth ELISA positive clones were obtained, from these five were also positive to seronetralization and immunodot. The clones recognize a 39.8Kda protein. Aditionally, a capture-ELISA was developed using the monoclonal antobodies from this research. This ELISA is useful to detect a reference as a field nm virus strain.
