Hapten function
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. The mechanisms of absence of immune response may vary and involve complex immunological interactions, but can include absent or insufficient co-stimulatory signals from antigen-presenting cells.

WebApr 11, 2024 · An epitope is usually a protein segment that contains 5-6 amino acids. In this way, a complete protein will have a variety of epitopes where specific antibodies will bind. Linear amino acid sequences are referred to as continuous epithelial. Discontinuous epitopes are amino acid sequences, the conformation of which is bent.
WebApr 9, 2024 · A hapten is a small molecule that by itself is not immunogenic but can act as an antigen when it binds to a larger protein molecule. The hapten then acts as an epitope on the protein. For example with penicillin and poison ivy allergies, the penicillin molecules and the oil urushiol from the poison ivy plant function as haptens, binding to ...
