The more complex the chemical composition of an antigen, the more immunogenic it is.

An antigen is a foreign substance that can stimulate an immune response, such as a toxin, microorganism, or any molecule that can bind to a B-cell receptor, T-cell receptor, or an antibody.

An immunogen is an antigen that stimulates the immune response.

<p>The five classes of antibodies are IgG, IgA, IgM, IgD, and IgE.</p> Signup and view all the answers

<p>The two main characteristics of antigens that determine their immunogenicity are size (the larger the molecular weight/size, the more immunogenic) and complexity (the more complex the antigen, the more immunogenic).</p> Signup and view all the answers
