| h antigen | <microbiology> Any bacteria which has a long flagella that is used for movement. The term is used by immunologists and serologists as a form of classification. (09 Oct 1997) |
|---|---|
| cystic fibrosis antigen | Now known to be MRP 8. See: calgranulins. (18 Nov 1997) |
| heart antigen | A diphosphatidyl glycerol that is found in the membrane of Treponema pallidum and is the antigen detected by the Wasserman test for syphilis. (18 Nov 1997) |
| S antigen | Viral antigen that remains in solution after the particles of virus have been removed by means of centrifugation; in the case of the influenza viruses, it is the internal helical structure, free of the external envelope. Synonym: S antigen. (05 Mar 2000) |
| proliferating cell nuclear antigen | Acidic nuclear protein (33 kD) highly expressed in dividing cells. Interacts with D type cyclins. (18 Nov 1997) |
| hepatitis-associated antigen | A term used for the surface antigen of hepatitis B virus before its nature was established. See: hepatitis B surface antigen. (05 Mar 2000) |
| hepatitis B antigen | Antigens of the virion of the hepatitis b virus or the dane particle, its surface, core and other associated antigens, like the hbe antigen. (12 Dec 1998) |
| hepatitis B core antigen | <virology> (HBcAb, HBcAg), the antigen found in the core of the Dane particle (which is the complete virus) and also in hepatocyte nuclei in hepatitis B infections. (05 Mar 2000) |
| hepatitis B e antigen | (HBeAb, HBe, HBeAg), an antigen, or group of antigen's, associated with hepatitis B infection and distinct from the surface antigen (HBsAg) and the core antigen (HBcAg); it is associated with the viral nucleocapsid. Its presence indicates that the virus is replicating and the individual is potentially infectious. (05 Mar 2000) |
| hepatitis B surface antigen | <virology> A serologic marker on the surface of the hepatitis B virus. The body will normally produce antibodies to hepatitis B surface antigen as part of the normal immune response to infection. It is the presence of antibodies to the hepatitis B surface antigen that are detected in a positive hepatitis B blood test. (27 Sep 1997) |
| heterogeneic antigen | An antigen or antigenic determinant which is found in different tissues in more than one species. (05 Mar 2000) |
| heterogenetic antigen | An antigen which is possessed by a variety of different phylogenetically unrelated species; e.g., the various organ-or tissue-specific antigen's, the alpha-and beta-crystalline protein of the lens of the eye, and Forssman antigen. Synonym: heterophil antigen. (05 Mar 2000) |
| heterogenic enterobacterial antigen | Cross reacting antigen (epitope), a common antigen that occurs in 2 or more different molecules/organisms. Synonym: heterogenic enterobacterial antigen. (05 Mar 2000) |
| heterophil antigen | An antigen which is possessed by a variety of different phylogenetically unrelated species; e.g., the various organ-or tissue-specific antigen's, the alpha-and beta-crystalline protein of the lens of the eye, and Forssman antigen. Synonym: heterophil antigen. (05 Mar 2000) |
| heterophile antigen | An antigen or antigenic determinant which is found in different tissues in more than one species. (05 Mar 2000) |
