hapten
hap·ten H0055200 (hăp′tĕn′) also hap·tene (-tēn′)n. A small molecule that reacts with a specific antibody but does not induce an immune response unless bound to a larger molecule, usually a protein.
[German : Greek haptein, to fasten + German -en, noun suffix (from Greek -ēnē, -ene).]
hap·ten′ic adj.hapten (ˈhæptən) or haptenen (Physiology) immunol an incomplete antigen that can stimulate antibody production only when it is chemically combined with a particular protein[C20: from German, from Greek haptein to fasten]hap•ten (ˈhæp tɛn) also hap•tene (-tin)
n. a substance that reacts with antibodies but cannot by itself stimulate more antibodies; a partial antigen. [1920–25; < German < Greek hápt(ein) to grasp + German -en -ene] hapten
hapten (immunology) An incomplete antigen that cannot induce antibody formation by itself but can do so by coupling with a larger carrier molecule. hapten
hapten [hap´ten] a small molecule, not antigenic by itself, that can react with specific antibodies and elicit the formation of such antibodies when conjugated to a larger antigenic molecule, usually a protein, called in this context the carrier. Antibody production involves activation of lymphocytes" >B lymphocytes by the hapten and helper T cells by the carrier.hap·ten (hap'-ten), A molecule that is incapable, by itself, of causing a cell-mediated or humoral immune response but can, however, combine with a larger antigenic molecule called a carrier. A hapten-carrier complex can stimulate antibody production and reactive T-cells.

A small molecule that reacts with a specific antibody but cannot induce the formation of antibodies unless bound to a carrier protein or other large antigenic molecule.
hap·ten′ic adj.hap·ten (hap'tĕn) A molecule that is incapable, alone, of causing the production of antibodies but can, however, combine with a larger antigenic molecule called a carrier.
Synonym(s): incomplete antigen, partial antigen. [G. haptō, to fasten, + -en, noun suffix]hapten An incomplete antigen that cannot, by itself, promote antibody formation but that can do so when conjugated to a protein. Most haptens are organic substances of low molecular weight. From the Greek haptein , to fasten.hapten a substance that is able to combine with specific antibodies but does not produce them unless attached to a large CARRIER MOLECULE.hap·ten (hap'tĕn) A molecule that is incapable, alone, of causing the production of antibodies but can, however, combine with a larger antigenic molecule called a carrier.
