| blood protein electrophoresis | Electrophoresis applied to blood proteins. (12 Dec 1998) |
|---|---|
| capillary electrophoresis | A technique for separating compounds, a sample of a compound to beseparated is placed in a capillary tube, which is then subjected to ahigh voltage current that separates its chemical components. (09 Oct 1997) |
| capillary zone electrophoresis | A method for separating molecules extremely rapidly based on their electrophoretic mobility. (05 Mar 2000) |
| gamaglobulin electrophoresis | <investigation> A test that detects and measures the various immunoglobulins in the blood. In the normal assay no monoclonal antibodies are detected. In multiple myeloma and chronic lymphocytic leukaemia a single clone of lymphocytes can produce one type of immunoglobulin that is detected in the electrophoresis as monoclonal (made by one cell clone). (27 Sep 1997) |
| gel electrophoresis | <molecular biology> Electrophoresis using a gel supporting phase. Usually applied to systems where the gel is based on polyacrylamide. See: electrophoresis. (05 May 1997) |
| carrier electrophoresis | Electrophoresis done on a carrier (such as paper, polyacrylamide gel, etc.). (05 Mar 2000) |
| cell electrophoresis | <technique> A method for estimating the surface charge of a cell by looking at its rate of movement in an electrical field. Almost all eukaryotic cells have a net negative surface charge. Measurement is complicated by the streaming potential at the wall of the chamber itself and by the fact that the cell is surrounded by a layer of fluid (see double layer). The electrical potential measured (the zeta potential) is actually some distance away from the plasma membrane. One of the more useful modifications is to systematically vary the pH of the suspension fluid to determine the pK of the charged groups responsible (mostly carboxyl groups of sialic acid).

| multi locus enzyme electrophoresis | Inhibition of translation of the transcript of a transposase gene by a multicopy plasmid with suitable inhibitory gene. The plasmid inhibits transposition events in the host bacterium. (18 Nov 1997) |
| polyacrylamide gel electrophoresis | Analytical and separative technique in which molecules, particularly proteins, are separated by their different electrophoretic mobilities in a hydrated gel. The gel suppresses convective mixing of the fluid phase through which the electrophoresis takes place and contributes molecular sieving. Commonly carried out in the presence of the anionic detergent sodium dodecylsulphate (SDS). SDS denatures proteins so that noncovalently associating sub unit polypeptides migrate independently and by binding to the proteins confers a net negative charge roughly proportional to the chain weight. See: SDS PAGE. (21 Jun 1999) |
| haemoglobin electrophoresis | <investigation> A special diagnostic procedure which identifies abnormal haemoglobin proteins by the way they migrate in an electric field (electrophoresis). The electric field is used to separate haemoglobin proteins from each other and allow the identification of different components. This can be used to diagnose thalassaemia, sickle cell disease and haemoglobin C disease. (18 Nov 1997) |
| pulsed-field gel electrophoresis | Gel electrophoresis in which, after electrophoretic migration has begun, the current is briefly stopped and reapplied in a different orientation; allows for the purification of long DNA molecules. Synonym: pulsed-field gel electrophoresis. (05 Mar 2000) |
| pulse field electrophoresis | <investigation> A method used for high resolution electrophoretic separation of very large (megabase) fragments of DNA. Electric fields 100 |
| pulse-field gel electrophoresis | Gel electrophoresis in which, after electrophoretic migration has begun, the current is briefly stopped and reapplied in a different orientation; allows for the purification of long DNA molecules. Synonym: pulsed-field gel electrophoresis. (05 Mar 2000) |
| serum immunoglobulin electrophoresis | A test that detects and measures the various immunoglobulins in the blood. In the normal assay no monoclonal antibodies are detected. In multiple myeloma and chronic lymphocytic leukaemia a single clone of lymphocytes can produce one type of immunoglobulin that is detected in the electrophoresis as monoclonal (made by one cell clone). (27 Sep 1997) |
| disc electrophoresis | Short for discontinuous electrophoresis, it is a type of polyacrylamide gel electrophoresis. This electrophoresis method uses gels of two different concentrations of polyacrylamide (a synthetic polymer), the one of lower concentration stacked on top of the one with higher concentration, in order to better resolve bands of whatever is being separated (DNA, RNA, or protein) that would otherwise be very close together.
