| primary immune response | <immunology> The immune response to the first challenge by a particular antigen. Usually less extensive than the secondary immune response, being slower and shorter lived with smaller amounts of lower affinity antibody being produced. (18 Nov 1997) |
|---|---|
| secondary immune response | The response of the immune system to the second or subsequent occasion on which it encounters a specific antigen. (18 Nov 1997) |
| humoral immune response | <immunology> Those immune responses mediated by antibody. (06 Mar 1998) |
| immune response | <immunology> Alteration in the reactivity of an organisms immune system in response to an antigen, in vertebrates, this may involve antibody production, induction of cell-mediated immunity, complement activation or development of immunological tolerance. (18 Nov 1997) |
| immune-response gene | <molecular biology> Any of several genes of the major histocompatibility complex that control the immune response of lymphocytes to specific antigens. (09 Oct 1997) |
| immune response genes | Gene's in the HLA-D region of the histocompatibility complex of human chromosome 6 which control the immune response to specific antigens. (05 Mar 2000) |
| acid soluble spore protein | <molecular biology> A DNA binding protein in the spores of some bacteria, thought to stabilise the DNA in an A configuration, so protecting it from cleavage by enzymes or UV light. (18 Nov 1997) |
| alcohol-soluble eosin | See: ethyl eosin. Synonym: alcohol-soluble eosin. (05 Mar 2000) |
| water-soluble chlorophyll derivatives | The copper complex of sodium and/or potassium salts of saponified chlorophyll, used topically for deodorization of chronic lesions and to promote wound repair. (05 Mar 2000) |
| soluble | 1. Susceptible of being dissolved in a fluid; capable of solution; as, some substances are soluble in alcohol which are not soluble in water. "Sugar is . . . Soluble in water and fusible in fire." (Arbuthnot) 2. Susceptible of being solved; as, a soluble algebraic problem; susceptible of being disentangled, unraveled, or explained; as, the mystery is perhaps soluble. "More soluble is this knot." 3. Relaxed; open or readily opened. "The bowels must be kept soluble." Soluble glass. <chemistry> See Glass. Origin: L. Solubilis, fr. Solvere, solutum, to loosen, to dissolve: cf. F. Soluble. See Solve, and cf. Solvable. Source: Websters Dictionary (01 Mar 1998) |
| soluble 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) |
| soluble glass | A silicate of potassium or sodium, soluble in hot water but solid at ordinary temperatures; used for fixed dressings. Synonym: water glass. (05 Mar 2000) |
| soluble gun cotton | <chemistry> A substance resembling gun cotton in composition and properties, but distinct in that it is more highly nitrified and is soluble in alcohol, ether, etc. Synonym: pyroxyle. Source: Websters Dictionary (01 Mar 1998) |
