Abstract
Methods and kits for identifying antigens from a pathogen. The antigens identified are preferably those that provide protection for an animal against the pathogen. The steps of the method include providing a sample of the pathogen, isolating the protective antigen from the sample of antigen with an antibody probe. The antibody probe is produced by obtaining a biological sample containing antibody producing cells from an immune animal infected with or challenged by the pathogen or pathogen extract, and obtaining the antibodies from these cells by culturing the cells. These methods and kits are useful for preparing antigens to be used as vaccines, in diagnostic kits, and to prepare polyclonal or monoclonal antibodies.
