This immunology course stresses the fundamental concepts of innate and specific immunity, including the biology of lymphocytes, the structure and diversity of antibodies, the applications of immunoassays, and clinical immunology such as hypersensitivity, immunodeficiencies and autoimmune disorders. Laboratory exercises include cell differentials, and various serological techniques such as production and purification of polyclonal antibodies, SDS polyacrylamide gel electrophoresis, Western blotting, ELISA, immunohistochemistry, flow cytometry and a variety of immunoprecipitations, agglutinations, and immunodiffusions.
