Abstract
A process and apparatus for treating a liquid protein mixture is disclosed in which the protein mixture is first determined by electrodialysis (ED) and then subjected to isoelectric focusing (IEF) to effect the separation of proteins based on differences in their isoelectric points (pI). This combination of ED-IEF results in an improved separation of the protein components of a mixture than without the ED step.
