This article reviews the development of immobilized-metal affinity chromatography (IMAC) and describes its most important applications. We provide an overview on the use of IMAC in protein fractionation and proteomics, in protein immobilization and detection, and on some special applications such as purification of immunoglobulins and the Chelex method. The most relevant application— purification of histidine-tagged recombinant proteins—will be reviewed in greater detail with focus of state-of-the-art materials, methods, and protocols, and the limitations of IMAC and recent advances to improve the technology and the methods will be described.
