| D antigen | One of 6 antigens that compose the Rh locus. Antibody induced by D antigen is the most frequent cause of haemolytic disease of the newborn. (05 Mar 2000) |

| delta antigen | A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis b and chronic hepatitis. Officially this is classified as a subviral satellite RNA (RNA, satellite). (12 Dec 1998) |
| Dharmendra antigen | A chloroform-ether extracted suspension of Mycobacterium leprae; used to produce the Fernandez reaction in a lepromin test. (05 Mar 2000) |
| Di antigen | diego blood group |
| differentiation antigen | Any large structural macromolecule that can be detected by immune reagents and that also is associated with the differentiation of a particular cell type or types. Many cells can be identified by their possession of a unique set of differentiation antigens. There should be no implication that the antigens cause differentiation. (18 Nov 1997) |
| Ia antigen | Antigens coded for by the I region of the MHC complex. The majority, if not all, such antigens are Class II molecules composed of _ and _ polypeptide chains. (18 Nov 1997) |
| incomplete antigen | <immunology, molecular biology> Could be considered an isolated epitope: although a hapten (by definition) has an antibody directed against it, the hapten alone will not induce an immune response if injected into an animal, it must be conjugated to a carrier (usually a protein). The hapten constitutes a single antigenic determinant, perhaps the best known example is dinitro phenol (DNP) that can be conjugated to BSA and against which antiDNP antibodies are produced (antibodies to the BSA can be adsorbed out). Because the hapten is monovalent, immune complex formation will be blocked if the soluble hapten is present as well as the hapten carrier conjugate (assuming there is more than one hapten per carrier then an immune precipitate can be formed). Competitive inhibition by the soluble small molecule is sometimes referred to as haptenic inhibition and this term has carried over into lectin mediated haemagglutination where monosaccharides are added to try to block haemagglutination: the blocking sugar defines the specificity of the lectin.

| InV group antigen | Allotypic antigens that are present on human kappa immunoglobulin light chains. Synonym: InV group antigen. (05 Mar 2000) |
| Ir associated antigen | Antigens coded for by IR (immune response) genes or antigens coded for by the genome close to the IR genes. See: Ia antigens. (18 Nov 1997) |

| O-antigen polymerase | <enzyme> Involved in the binding of o-antigen repeat units and in polymerizing into the o-antigen chain; mw 43.7 kD; genbank x71970 Registry number: EC 2.4.1.- Synonym: rfc protein, s. Flexneri, rfc gene product, o-antigen polymerase, shigella, o-antigen polymerase, pseudomonas, rfc protein, pseudomonas, o-antigen polymerase, e. Coli (26 Jun 1999) |
| Tac antigen | An antigenic determinant of the human interleukin 2 receptor that is identified by a murine monoclonal antibody, anti-Tac. Binding of this antigen prevents the proliferation of T-cells, which is normally stimulated by binding interleukin-2. (05 Mar 2000) |
| T antigen | <molecular biology> Proteins coded by viral genes that are expressed early in the replication cycle of papovaviruses such as SV40 and polyoma. Essential for normal viral replication, they are also expressed in nonpermissive cells transformed by these viruses. Originally detected as Tumour antigens by immunofluorescence with antisera from tumour bearing animals. SV40 has two, large T and small t, polyoma has three, large, middle and small. Appear to be collectively responsible for transformation by these viruses. (14 Oct 1997) |
