| heterophile antibody | <immunology> An antibody raised against an antigen from one species that also reacts against antigens from other species. Also used of Forssman type systems where antibody against antigens from a variety of species is present without immunisation. (18 Nov 1997) |
|---|---|
| heterospecific antibody | <immunology> Artificially produced antibody in which the two antigen binding sites are for different antigens. (18 Nov 1997) |
| secondary antibody deficiency | Immunodeficiency in which there is no evident defect in the lymphoid tissues, but rather hypercatabolism or loss of immunoglobulins such as occurs in familial idiopathic hypercatabolic hypoproteinaemia or in defects associated with the nephrotic syndrome. Synonym: secondary agammaglobulinaemia, secondary antibody deficiency, secondary hypogammaglobulinaemia. (05 Mar 2000) |
| secondary antibody response | An antibody made upon second (subsequent) exposure to an antigen, mostly of the class IgG. (09 Oct 1997) |
| homocytotropic antibody | <immunology> A type of antibody which is able to attach itself to the surfaces of cells without needing specific combining sites. A homocytotropic antibody will only bind to cells which are from the same species as itself. (09 Oct 1997) |
| hybrid antibody | <immunology> Artificially produced antibody made by fusing hybridomas producing two different antibodies, the hybrid cells produce three different antibodies, only one of which is a heterophilic antibody. Can also be prepared chemically from two antibodies. (18 Nov 1997) |
| hyperimmune antibody | An antibody which occurs in a hyperimmune individual and which targets the antigen that has brought on the hyperimmunity. (09 Oct 1997) |
| natural antibody | Antibody demonstrable in the serum or plasma of various persons or animals not known to have been stimulated by specific antigen, either artificially or as the result of naturally occurring contact. Synonym: natural antibody. (05 Mar 2000) |
| neutralizing antibody | A form of antibody that reacts with an infectious agent (usually a virus) and destroys or inhibits its infectivity and virulence; may be demonstrated by means of mixing serum with the suspension of infectious agent, and then injecting the mixture into animals or cell cultures that are susceptible to the agent in question. (05 Mar 2000) |
| nonprecipitable antibody | Antibody that, under conditions normally employed in precipitin tests, is refractory to precipitation by specific antibody, demonstrable when antigen is added serially in small amounts; nonprecipitating antibody will precipitate under special conditions such as addition of complement. Synonym: nonprecipitable antibody. (05 Mar 2000) |
| nonprecipitating antibody | Antibody that, under conditions normally employed in precipitin tests, is refractory to precipitation by specific antibody, demonstrable when antigen is added serially in small amounts; nonprecipitating antibody will precipitate under special conditions such as addition of complement. Synonym: nonprecipitable antibody. (05 Mar 2000) |
| normal antibody | Antibody demonstrable in the serum or plasma of various persons or animals not known to have been stimulated by specific antigen, either artificially or as the result of naturally occurring contact. Synonym: natural antibody. (05 Mar 2000) |
| syndrome, antiphospholipid antibody | An immune disorder characterised by the presence of abnormal antibodies in the blood associated with certain medical conditions including abnormal blood clotting, migraine headaches, premature miscarriage, and low blood platelet counts (thrombocytopenia). (12 Dec 1998) |
| direct fluorescent antibody | The straightforward detection of antigens using fluorescent labelled antigen-specific antibody. Because detection of the antigen in a substrate of patient sample (cellular smear, fluid or patient-inoculated culture medium) is the goal, direct fluorescent antibody is seldom quantitative. (05 Mar 2000) |
| direct fluorescent antibody test | Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (fluorescent antibody technique, direct) or an indirect method, by formation of antigen-antibody complex which is then labelled with fluorescein-conjugated anti-immunoglobulin antibody (fluorescent antibody technique, indirect). The tissue is then examined by fluorescence microscopy. (12 Dec 1998) |
