Immobilized metal affinity chromatography (IMAC) is used primarily in the purification of polyhistidine tagged recombinant proteins. This is achieved by using the natural tendency of histidine to chelate divalent metals. Placing the metal ion on a chromatographic support allows purification of the histidine tagged proteins but the concept is plagued by the inability to discriminate between the recombinant protein and other host proteins that happen to have available histidines. We apply our knowledge of time tested solutions to this problem to obtain a purification process that will dramatically minimize the host protein contamination of your purified protein.
