Category: Chromatography Protocols: Immobilized Metal Ion Affinity Chromatography Protocols

Protocol for the optimization of imidazole concentrations for immobilized metal-ion affinity chromatography. Most samples from which histidine-tagged proteins are to be purified also contain endogenous protein contaminants that bind to the immobilized metal-ion affinity chromatography (IMAC) adsorbent.  Usually, these proteins bind more weakly than the histidine-tagged protein. - [Read Optimization of Imidazole Concentrations for Immobilized Metal-Ion Affinity Chromatography Protocol]
