An analytical or separation procedure similar to gel electrophoresis. It is used to separate proteins and other charged molecules on the basis of their isoelectric point. A series of ampholytes are used to establish a pH gradient within a support gel. The charged molecules migrate through the gel until they reach an equilibrium point at which they carry no net charge and thus are not affected by the electric field across the gel. 1, record 1, English, - isoelectric%20focusing

Méthode de séparation très résolutive des protéines qui repose sur la distinction de ces macromolécules selon leur point isoélectrique(pHi). Chaque protéine en effet, comme n’ importe quel ampholyte, est définie par son point isoélectrique, valeur du pH du milieu pour lequel sa charge électrique résultante est nulle. Placée à un pH supérieur à son pHi la protéine se charge négativement par perte de protons. A un pH inférieur au pHi, la protéine se charge positivement par capture de protons. Sous l'influence d’un champ électrique continu, les protéines migrent vers la zone de pH "en équilibre" avec leur pH isoélectrique, c'est-à-dire dans la zone où elles seront électriquement neutres. 2, record 1, French, - %C3%A9lectrofocalisation

Electrophoresis in a stabilised pH gradient. High-resolution method for separating molecules, especially proteins, which carry both positive and negative charges. Molecules migrate to the pH corresponding to their isoelectric point. The gradient is produced by electrophoresis of amphiphiles, which are 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. 3, record 8, English, - isoelectric%20focusing

The power of isoelectric focusing is extraordinary: it can resolve the proteins of human blood plasma into 40 or more bands.... The method is generally used on an analytical scale, although it is possible to scale up for preparative work (up to gram quantities). 4, record 8, English, - isoelectric%20focusing
