| 설명 | 1. 일반적으로 액체 속에 존재하는 작은 고체가 액체 바닥에 가라앉아 쌓이는 일. 2. 화학에서는 시약을 가하거나 가열-냉각 등에 의하여 일어나는 화학변화의 생성물이 용액 속에 나타나는 현상, 또는 용질이 포화에 도달하여 용액 속에 나오는 것을 말한다. 또, 이때 생긴 고체를 침전물이라고 한다. 침전생성법은 물질의 분리-정제 또는 분석에 흔히 사용되며 화학실험에서 중요한 조작이다. |

cyto-inhibition
| hapten inhibition of precipitation | Inhibition of precipitation that occurs when the precipitin has combined with hapten of the same specificity as the subsequently added antigen. (05 Mar 2000) |
|---|
| conjugated hapten | A hapten that may cause the production of antibodies when it has been covalently linked to protein. Synonym: conjugated antigen. (05 Mar 2000) |
|---|---|
| half-hapten | A substance that elicits an antigen-antibody reaction, but no precipitation. (05 Mar 2000) |
| hapten | <immunology, molecular biology> Could be considered an isolated epitope: although a hapten (by definition) has an antibody directed against it, the hapten alone will not induce an immune response if injected into an animal, it must be conjugated to a carrier (usually a protein). The hapten constitutes a single antigenic determinant, perhaps the best known example is dinitro phenol (DNP) that can be conjugated to BSA and against which antiDNP antibodies are produced (antibodies to the BSA can be adsorbed out). Because the hapten is monovalent, immune complex formation will be blocked if the soluble hapten is present as well as the hapten carrier conjugate (assuming there is more than one hapten per carrier then an immune precipitate can be formed). Competitive inhibition by the soluble small molecule is sometimes referred to as haptenic inhibition and this term has carried over into lectin mediated haemagglutination where monosaccharides are added to try to block haemagglutination: the blocking sugar defines the specificity of the lectin. (18 Nov 1997) |
| Forssman hapten | A glycolipid from mammalian organs. Compare: Forssman antibody, Forssman antigen. (05 Mar 2000) |
| ammonium sulphate precipitation | <technique> In this technique, ammonium sulphate is used to make proteins precipitate out of a solution, the proteins are then collected by centrifugation. (09 Oct 1997) |
| capsular precipitation reaction | Swelling of the capsule surrounding a bacterium as a result of interaction with anticapsular antibody, consequently the capsule becomes more refractile and conspicuous. (18 Nov 1997) |
| precipitation | The act or process of precipitating. Origin: L. Praecipitatio (18 Nov 1997) |
| precipitation curve | A graph of the quantity of precipitate formed as a function of the quantity of antigen added during the titration of an antibody with an antigen. Synonym: Heidelberger curve. (05 Mar 2000) |
| precipitation test | An in vitro test in which antigen is in soluble form and precipitates when it combines with added specific antibody in the presence of an electrolyte. See: gel diffusion precipitin tests, ring precipitin test. Synonym: precipitation test. (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) |
| immune precipitation | <immunology> The precipitation of a multivalent antigen by a bivalent antibody, resulting in the formation of a large complex. The antibody and antigen must be soluble. Precipitation usually occurs when there is near equivalence between antibody and antigen concentrations. (18 Nov 1997) |
| isopropanol precipitation test | A test using the principle that the internal bonds of haemoglobin are weakened by nonpolar solvents; thus, unstable haemoglobins will precipitate more rapidly than other haemoglobins in isopropanol. (05 Mar 2000) |
| allogeneic inhibition | Inhibition or injury to allogeneic cells that occurs when lymphocytes are mixed and cultured with other cells of different genotypes in vitro. (05 Mar 2000) |
| macrophage inhibition factor | <cytokine> A group of lymphokines (including a 14 kD glycoprotein) produced by activated T lymphocytes that reduces macrophage mobility and probably increases macrophage macrophage adhesion. (18 Nov 1997) |
| macrophage migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |
