Significant efforts are put into the design of large-scale purification processes of proteins due to great demands regarding cost efficiency and safety. In order to design an effective purification scheme the unit operations need to be reduced to a minimum. In this review we are discussing proteinaceous ligands as well as small synthetic mimics for use in affinity chromatography for large-scale applications. Different advantages as well as drawbacks of the two approaches are outlined.
