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 ...

Until recently, there have been a number of problems associated with immobilized pH gradient-isoelectric focusing (IPG-IEF) for 2-D electrophoresis. Numerous manipulations of the IPG strips introduce ...

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.
