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 ...

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 ...

With the FOCUSING option, the agarose gel electrophoresis systems are also equipped with a high-voltage module allowing for isoelectric focusing (IEF) testing to be performed.
