IMAC, which can be carried out under denaturing or nondenaturing conditions, relies on the interaction between multiple electron donors on the affinity tag with a transition metal ion (Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ ) chelated to a solid-phase support Immobilized metal ion affinity chromatography (IMAC) (1,2) is also referred to as metal chelate chromatography, metal ion interaction chromatography, and ligand-exchange chromatography. We view this affinity separation technique as an intermediate between highly specific, high-affinity bioaffinity separation methods, and wider spectrum, low-specificity adsorption methods, such as ion exchange. The IMAC stationary phases are designed to chelate certain metal ions that have selectivity for.

Immobilized metal ion affinity chromatography (IMAC) is based on the specific coordinate covalent bond of amino acids, particularly histidine, to metals. This technique works by allowing proteins with an affinity for metal ions to be retained in a column containing immobilized metal ions, such as cobalt, nickel, copper for the purification of histidine-containing proteins or peptides, iron, zinc or gallium for the purification of phosphorylated proteins or peptides. Many naturally. Proteins and peptides that have an affinity for metal ions can be separated using metal chelate affinity chromatography. The metals are immobilized onto a chromatographic medium by chelation. Certain amino acids, e.g. histidine and cysteine, form complexes with the chelated metals around neutral pH (pH 6-8) and it is primarily the histidine-content of a protein which is responsible for its binding to a chelated metal

and Immobilized Ions The concept of immobilized-metal affinity chromatography (IMAC) has first been formulated and its feasibility shown by Porath et al. (1975). It was based on the known affinity of transition metal ions such as Zn2þ, Cu2þ,Ni2þ, and Co2þ to histidine and cysteine in aqueous solution Immobilized metal-ion affinity chromatography (IMAC) used to purify recombinant proteins features a resin-bound 1:1 Ni(II)-iminodiacetic acid (IDA) complex.

A common chelating group is. Because affinity chromatography is recognizing something unnatural and highly specific, it can (hopefully) remove most contaminating proteins - but not all. A common affinity tag is a His tag, which is just 6 or 8 Histidines, which will bind to a Nickel (Ni) or Cobalt (Co) coated column (Immobilized Metal Affinity Chromatography; IMAC) Immobilized metal-ion affinity chromatography (IMAC) (1, 2, 3, 4) is also referred to as metal chelate chromatography, metal-ion interaction chromatography, and ligand-exchange chromatography.
