The classical method for generating polyclonal or monoclonal antibodies relies on the in vivo humoral response of animals. Here we describe the factors that antigens can have that might influence the strength and quality of an antibody response. This introduction is divided into three sections: (1) an overview of immunogenicity, (2) choosing the best form for the immunogen, and (3) methods for modifying antigens to make them more immunogenic.
