Highly complex carbohydrates can be immunogenic. (2) Lipids are poor immunogens and act as happens when attached to proteins.

What are examples of immunogens?

We can define an immunogen as a complete antigen which is composed of the macromolecular carrier and epitopes (determinants) that can induce immune response. An explicit example is a hapten. Haptens are low-molecular-weight compounds that may be bound by antibodies, but cannot elicit an immune response.

What are the characteristics of an immunogen?

Properties determining immunogenicity

Immunogenicity is the ability of a molecule to solicit an immune response. There are three characteristics that a substance must have to be immunogenic: foreignness, high molecular weight and chemical complexity.
