| viral antigen | Those antigens specified by the viral genome (often coat proteins) that can be detected by a specific immunological response. Often of diagnostic importance. (18 Nov 1997) |
|---|---|
| C carbohydrate antigen | An antigen found in the cell wall of Streptococcus pneumoniae. See: beta-haemolytic streptococci. (05 Mar 2000) |
| CD antigen | <immunology> Differentiation antigens residing on human leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similiar reactivity with certain subpopulations of antigens. The subpopulations of antigens are also known by the same CD designation. (12 Dec 1998) |
| Rhus toxicodendron antigen | An extract of fresh leaves of poison ivy, with 0.4% of procaine hydrochloride; used by intradermal injection to determine sensitiveness to the poison of Rhus toxicodendron. (05 Mar 2000) |
| Rhus venenata antigen | An extract of fresh leaves of poison sumac; used to determine sensitiveness to the plant or to relieve the dermatitis caused by contact with its leaves. (05 Mar 2000) |
| cholesterinised antigen | Cardiolipin to which cholesterol has been added. (05 Mar 2000) |
| rotavirus antigen test | <investigation, microbiology> A test which detects the presence of rotavirus in the stool. This virus is a common cause of childhood gastroenteritis. (17 Dec 1997) |
| Mitsuda antigen | An autoclaved suspension of human tissue naturally infected with Mycobacterium leprae; used to produce the Mitsuda reaction in a lepromin test. (05 Mar 2000) |
| common antigen | Cross reacting antigen (epitope), a common antigen that occurs in 2 or more different molecules/organisms. Synonym: heterogenic enterobacterial antigen. (05 Mar 2000) |
| 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) |
