A small molecule which can act as an epitope but is incapable by itself of eliciting an antibody response.
Low-molecular-weight molecule that contains an antigenic determinant (epitope) that may bind to a specific antibody but which is not itself antigenic unless complexed with an antigenic carrier such as a protein or cell; once bound it can cause the sensitization of lymphocytes, possibly leading to allergy or cell-mediated hypersensitivity. After Nagel et al. (eds), 1991 RT allergy, antigen, antibody, cell-mediated hypersensitivity, epitope.
A small molecule that is not immunogenic unless attached to a carrier protein.
A substance not inducing antibody formation but able to combine with a specific antibody.
A molecule (usually a small organic molecule) which can be bound to an antigenic determinant/ epitope. Usually they are too small to give a response of their own. They become antigenic if they are coupled to a suitable macromolecule, such as a protein. [IUPAC Bioinorganic] [Go to source
a molecule containing one or more epitopes that does not stimulate a host's immune system to make a humoral or cellular response unless linked to a carrier
a molecule or portion thereof that has little or no antigenicity unless coupled to a carrier molecule that is antigenic
a small molecule that acts as an antigen when conjugated to a protein
a small molecule that by itself is not immunogenic but can act as an antigen when it binds to a larger protein molecule
a small substance that has reactivity but lacks immunogenicity
a term used to describe a single, isolated antigenic determinant
A small molecule which when bound to a protein can induce the formation of an antibody in vivo.
A compound, usually of low molecular weight, that is not itself immunogenic but that, after conjugation to a carrier protein or cells, becomes immunogenic and induces antibody, which can bind the hapten alone in the absence of carrier.
A partial antigen that can bind to an antibody but cannot stimulate antibody production; a foreign compound that has only one antigenic determinant site.
a non-protein substance that can evoke an immune response through combination with a carrier protein. On its own, however, it is not antigenic.
A hapten is a small molecule which can elicit an immune response only when attached to a large carrier such as a protein; the carrier may be one which also does not elicit an immune response by itself. (Generally, only large molecules, infectious agents, or insoluble foreign matter can elicit an immune response in the body.) Once the body has generated antibodies to a hapten-carrier adduct, the small-molecule hapten may also be able to bind to the antibody, but it will usually not initiate an immune response; usually only the hapten-carrier adduct can do this.
