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. WebAn antigen is a marker that tells your immune system whether something in your body is harmful or not. Antigens are found on viruses, bacteria, tumors and normal cells of your body. Antigen testing is done to diagnose viral infections, monitor and screen for certain conditions and determine whether a donor is a good match for a transplant.
