| complete antigen | Any antigen capable of stimulating the formation of antibody with which it reacts in vivo or in vitro, as distinguished from incomplete antigen (hapten). (05 Mar 2000) |
|---|---|
| conjugated antigen | A hapten that may cause the production of antibodies when it has been covalently linked to protein. Synonym: conjugated antigen. (05 Mar 2000) |
| mumps skin test antigen | A sterile suspension of killed mumps virus in isotonic sodium chloride solution, used to determine susceptibility to mumps or to confirm previous exposure. (05 Mar 2000) |
| pollen antigen | An extract of the antigenic protein from the pollen of plants; i.e., pollen allergen, used in the diagnosis and prevention of hay fever. (05 Mar 2000) |
| H-2 antigen | <immunology> Antigen coded in the major group of transplantation antigens in the mouse. See: H-2 complex, histocompatability antigen. (20 Jun 2000) |
| 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) |
