Iso-electric focusing: A technique for separating proteins according to their iso-electric points. The mixture of proteins is placed in a pH gradient established by ampolines in an electric field across a liquid or a gel matrix; the proteins move in the electric field until they reach their iso-electric points in the pH gradient where, having lost net charge, they are focused. 2, record 3, English, - isoelectric%20point
