One specific type of electrophoresis is isoelectric focusing (IEF), which separates amphoteric compounds (molecules that can act as either acids or bases) in a pH gradient. Recent research has ...

Isoelectric focusing (IEF) separates proteins in a pH gradient. Each protein is 'focused' because it moves under the influence of the electric field until it reaches its isoelectric point ...

Fractions are automatically collected by this instrument and then analyzed. An alternative method for separating by charge is in-solution isoelectric focusing. The Sample Preparation lab has two ...
