|---|---|---|---|
| 설명 | 전기운동적 현상의 하나로서 전장에서 양극이나 음극으로 향하는 입자의 운동을 이용하여 물질의 분석이나 정량에 이용하는 방법. 용액 속에서 전극에 전압을 가하면 그 입자가 음성 전기를 띠고 있으면 양극으로, 그리고 양성 전기를 띠고 있으면 음극으로 전기의 힘을 받아서 이동이 된다. 이동하는 모양도 입자의 형태나 크기에 따라 다르므로 단백질의 분석에 이용될 수가 있다. 이동속도는 입자자체의 전하 및 크기, 분자구조를 비롯하여 용매의 종류, 지지체 물질과의 상호작용, 온도 등에 의해 영향을 받게 된다. 전기이동은 이동도의 차이에 의해서 물질의 분리, 정제, 확인, 순도의 검정 등을 시행하는 것이다. |

| isoelectric focusing | <technique> Electrophoresis in a stabilised pH gradient. High resolution method for separating molecules, especially proteins, that carry both positive and negative charges. Molecules migrate to the pH corresponding to their isoelectric point. The gradient is produced by electrophoresis of amphiphiles, heterogenous molecules giving a continuum of isoelectric points. Resolution is determined by the number of amphiphile species and the evenness of distribution of their isoelectric points. (18 Nov 1997) |
| isoelectric line | The baseline of the electrocardiogram. (05 Mar 2000) |
| isoelectric period | The period occurring in the electrocardiogram between the end of the S wave and the beginning of the T wave during which electrical forces are acting in directions such as to neutralise each other so that there is no difference in potential under the two electrodes. (05 Mar 2000) |
| isoelectric point | <biochemistry> The pH at which a protein carries no net charge. Below the isoelectric point proteins carry a net positive charge, above it a net negative charge. Due to a preponderance of weakly acid residues in almost all proteins, they are nearly all negatively charged at neutral pH. The isoelectric point is of significance in protein purification because it is the pH at which solubility is often minimal and at which mobility in an electrofocusing system is zero (and therefore the point at which the protein will accumulate). (18 Nov 1997) |
| isoelectric zone | The range of H-ion concentration (pH) over which isoelectric precipitation occurs. (05 Mar 2000) |
| agarose gel electrophoresis | <procedure> A type of electrophoresis that uses a matrix of highly purified agar to separate large nucleotides in size. (06 May 1997) |
| 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). (26 Mar 1998) |
| 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) |
