How to choose different ligands in IMAC?

NTA and IDA are the two most widely used ligands in IMAC. NTA is a tetravalent ligand with coordination number 4 and therefore stronger coordination of metal ions, while IDA is a trivalent ligand with coordination number 3. Generally, NTA gives higher binding specificity and lower metal ion leaching, while IDA shows more non-specific binding and increased metal ion leaching. IDA can have higher metal ion loading density and usually requires much lower imidazole concentration in eluent.

As many factors can affect the choice of optimal ligand-metal ion combination, the best approach is to try different combinations and let your proteins decide. FastSep(TM) high performance resins and cartridges offer numerous ligand-metal ion combinations to meet various purification needs. FastSep(TM) high performance resins and chromatography cartridges are based on highly cross-linked agarose 6% beads which have structural characteristics that result in superb physical strength, excellent flow properties, low backpressure, and an open pore structure. FastSep(TM) high performance resins and chromatography cartridges allow operation at very high flow rates, resulting in increased throughput and rapid column cleaning between chromatography runs.
