Metal chelate affinity chromatography is a rapid one-step purification, which removes most contaminants and can achieve purities close to homogeneity. The rapid purification protocols provided in this handbook for affinity chromatography permit the recovery of high levels of pure recombinant protein in minutes. Recombinant proteins purified using Ni- NTA Affinity Resin - Amintra may be used in a wide range of structure and activity-based laboratory procedures.\u003cbr\u003e\nImmobilized Metal Affinity Chromatography (IMAC) technology was introduced by Porath et al (1975). The matrix is attached to chelating groups that immobilize transition metal ions such as Ni\u003cbr\u003e\n(Porath and Olin, 1983; Porath, 1988; Sulkowski, 1989). Certain amino acids such as histidine, tryptophan, cysteine and tyrosine can act as electron donors on the surface of the protein and bind reversibly to the transition metal ion. In the vast majority of instances, 6x histidine tag is engineered at the N or C terminus of the protein (Kd-10-13 at pH 8.0).\u003cbr\u003e\nis the most widely used metal ion as most IMAC tags seem to have very high affinity for immobilized Ni\u003cbr\u003e\n. The simplicity of IMAC technology is extremely attractive as it lends itself to the bind, wash and elute mode of operation if the appropriate buffer formulations are selected. IMAC can often be used with samples without any pre-treatment e.g. buffer exchange step. The use of metal chelate affinity is widespread for the selective adsorption of engineered recombinant proteins and has largely superseded non-affinity methods of chromatography for purifying recombinant proteins.\u003cbr\u003e\nCharacteristics of the resin:\u003cbr\u003e\nSupporting matrix\u003cbr\u003e\nHighle cross-lined 6% agarose\u003cbr\u003e\nCharged metal ion\u003cbr\u003e\nBead size range\u003cbr\u003e\n45-165 μm\u003cbr\u003e\nRecommended working pH\u003cbr\u003e\npH 2.0-12.0\u003cbr\u003e\nStatic binding capacity\u003cbr\u003e\n\u0026gt;40 mg 6x His-tagged\u003cbr\u003e\nMaximum pressure\u003cbr\u003e\n0.3 MPa (3 bar)\u003cbr\u003e\nChemical stability\u003cbr\u003e\nSolubility in water\u003cbr\u003e\nInsoluble\u003cbr\u003e\nThis product is manufactured by Expedeon, an Abcam company and was previously called Amintra Ni-NTA Affinity Resin.
