IMMUNOLOGY

Detailed explanation-1: -Therefore, although haptens need a carrier molecule to become immunogenic, they are also antigenic as they are able to bind to antibodies or other components of the immune response primed by the hapten-carrier molecule complex.

Detailed explanation-2: -Haptens (derived from the Greek haptein, meaning “to fasten”) are small molecules that elicit an immune response only when attached to a large carrier such as a protein; the carrier may be one that also does not elicit an immune response by itself.

Detailed explanation-3: -Carrier proteins for immunogen preparation A carrier protein is any protein used for coupling with peptides or other haptens that are not sufficiently large or complex on their own to induce an immune response and produce antibodies.
