| 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) |
| acid-base equilibrium | A condition in which the net rate of acid or alkali production by the body is balanced by the net rate of acid or alkali excretion from the body, resulting in a stable concentration of hydrogen ions in the body fluids. (12 Dec 1998) |
| radioactive equilibrium | <radiobiology> That condition in which the activities of the members of a radioactive chain decrease exponentially in time with the half-life of the chain precursor. Such radioactive equilibrium is only possible when the half-life of the precursor is longer than that of any other chain member. If the precursor half-life is so long that the change in the precursor population during the period of interest can be ignored, all the activities become sensibly equal and the equilibrium is said to be secular, otherwise it is said to be transient. (16 Dec 1997) |
| random mating equilibrium | <genetics> In a population containing the genotypes of AA, aa, and Aa, the frequency of AA will be p2, the frequency of aa will be q2, and the frequency of Aa will be 2 pq at equilibrium, where p is the frequency of A and q is the frequency of a. By the Hardy-Weinberg law, a ramdonly-mating population will eventually reach these frequencies and be at this equilibrium as long as there are no selection pressures on the population. (09 Oct 1997) |
| genetic equilibrium | A condition in which the rate of an allele's forward mutation is cancelled out by its rate of reverse mutation. (09 Oct 1997) |
| Gibbs-Donnan equilibrium | An equilibrium established between a charged, immobile colloid (such as clay, ion exchange resin or cytoplasm) and a solution of electrolyte. Characteristics: ions of like charge to the colloid tend to be excluded, ions of opposite charge tend to be attracted, the colloid compartment is electrically polarized relative to the solution in the same direction as the colloid charges (a Donnan potential) and the osmotic pressure is higher in the colloid compartment. (18 Nov 1997) |
| chemical equilibrium | <chemistry> A state in a reversible chemical reaction at which the reactants are turning into products at the same rate as the products are turning back into the reactants, so that the amounts of each reactant and product remains constant. (09 Oct 1997) |
| physiologic equilibrium | nutritive equilibrium |
| Hardy-Weinberg equilibrium | <genetics> In a population containing the genotypes of AA, aa, and Aa, the frequency of AA will be p2, the frequency of aa will be q2, and the frequency of Aa will be 2 pq at equilibrium, where p is the frequency of A and q is the frequency of a. By the Hardy-Weinberg law, a ramdonly-mating population will eventually reach these frequencies and be at this equilibrium as long as there are no selection pressures on the population. (09 Oct 1997) |
| secular equilibrium | A type of radioactive equilibrium in which the half-life of the precursor (parent) radioisotope is so much longer than that of the product (daughter) that the radioactivity of the daughter becomes equal to that of the parent with time. Stable equilibrium, equilibrium in which, after every small perturbation, the original state will tend to be restored. Transient equilibrium, a type of radioactive equilibrium in which the half-life of the parent radioisotope is longer than that of the daughter so that the ratio of activities of parent and daughter become constant as they decrease with time. Unstable equilibrium, equilibrium in which the response to a small perturbation will tend to make the perturbation greater (e.g., a logged feedback process of zero order). (05 Mar 2000) |
