Abstract:The Rotofor cell is a preparative isoelectric focusing (IEF) apparatus, in which IEF is performed entirely in free solution. Electrofocusing in Rotofor cell has been described as well-suited for use at any stage of a purification scheme. However, it has some important limitations in resolving complex mixtures of proteins. This paper describes the advantages and disadvantages of using the Rotofor cell in purification protocols.
Keywords:Rotofor  Superoxide dismutase  6-phosphogluconate  dehydrogenase
