Immunological techniques are the wide varieties of methods and specialized experimental protocols devised by immunologists for inducing, measuring, and characterizing immune responses. They allow the immunologists to alter the immune system through cellular, molecular and genetic manipulation. These techniques are not restricted to the field of immunology, but are widely applied by basic scientists in many other biological disciplines and by clinicians in human and veterinary medicine.

Most immunological techniques available are focused on the study of the adaptive immune system. They classically involve the experimental induction of an immune response using methods based on vaccination protocols. During a typical experiment called immunization, immunologists inject a test antigen to an animal or human subject and monitor for the appearance of immune responses in the form of specific antibodies and effector T cells. Monitoring the antibody response usually involves the analysis of crude preparations of...
