Abstract: Affinity separation technology plays an increasingly important role in the proteins separation and purification field. Development of an appropriate ligand is the critical factor for affinity separation technology. In this work,the current research progress of the affinity ligand is reviewed according to three categories i.e. biological macromolecules affinity ligands,small molecule affinity ligands and metal iron affinity ligand. The current progress of each kind of ligand,its action mechanism and its deficiency are highlighted. Also,the prospect for development of affinity ligands is also given.

Key words: Specific adsorption, affinity, purification, chromatography, ligand
