Production of polyclonal antibodies against the cellular IFN-gamma receptor.

In this work we consider the possibility to produce a polyclonal antibody against murine interferon gamma receptors by immunizing rabbits with the complex receptor-IFN-gamma immunoprecipitated by a monoclonal antibody (AN-18) recognising the ligand bound to the receptor. Using the Western Blotting technique it has been found a polyclonal serum directed against a protein (90 kDa) that could represent the murine IFN-gamma membrane receptor.
