Imidazole Recrystallized by Molecular Depot is a recrystallised imidazole, the heterocycle that forms the side chain of histidine. Imidazole competes with a histidine tag for the metal on an affinity resin, which is how a tagged protein is eluted, and it also buffers around pH 7 where few other simple compounds do. It is used to elute histidine-tagged proteins from metal affinity resins, as a buffering agent near neutral pH and in organic synthesis. Each unit contains 2 g. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
