| 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) |
| double antibody immunoassay | A method of separating antibody-bound antigen (e.g., insulin) from free antigen by precipitating the former with antibody specific for immunoglobulin. Synonym: double antibody immunoassay, double antibody method. (05 Mar 2000) |
| double antibody method | A method of separating antibody-bound antigen (e.g., insulin) from free antigen by precipitating the former with antibody specific for immunoglobulin. Synonym: double antibody immunoassay, double antibody method. (05 Mar 2000) |
| double antibody precipitation | A method of separating antibody-bound antigen (e.g., insulin) from free antigen by precipitating the former with antibody specific for immunoglobulin. Synonym: double antibody immunoassay, double antibody method. (05 Mar 2000) |
| double antibody sandwich assay | For antigen; an application of the ELISA method in which material being tested for antigen is added to wells coated with known antibody; the presence of antigen fixed to the antibody coat can be determined either directly, by adding human antibody linked to the enzyme of the indicator system, or indirectly, by first adding unlabelled known antibody, the attachment of which to the antigen can be demonstrated by addition of immunoglobulin-specific antibody linked to the enzyme.
