To function properly, an immune system must detect a wide variety of agents, from viruses to parasitic worms, and distinguish them from the organism’s own healthy tissue. . Types of Antigen. Complete Antigen: Substances which can induce antibody formation by themselves. . Haptens: substances which are unable to induce antibody formation on its own but can become immunogenic, i.e., capable of inducing antibodies, when covalently linked to proteins known as carrier proteins..
