Immobilized Metal Ion Affinity Chromatography (IMAC) with Ni2+ is the standard method for purifying proteins with a lot of surface histidine or for engineered His-tagged proteins.
The (His)6-tag has become the most used affinity tag due to its small size, strong metal ion binding and ability to bind also under denaturing conditions.
How could you create a his tag?
with high Zn+2 affinity
How is this specificity mediated?
Complementarity: receptor/ligand binding is essentially pattern recognition between two complementary surfaces.
