Imidazole is a planar 5-membered ring. It is a highly polar, highly water soluble amphoteric compound. Imidazole is often used to elute tagged proteins bound to metal ions attached to the surface of beads in a chromatography column by displacing the His-tag from the metal ion and freeing the His-tagged proteins. Imidazole is also commonly used as a buffer for enzymatic reactions and has a buffering pH range of 6.2 - 7.8.
Recrystallized Imidazole from GoldBio is specially purified Imidazole designed for histidine tagged protein purification. We purify the Imidazole at Gold Biotechnology’s labs and go through multiple purification steps including ultrafiltration and recrystallization to obtain the most purified Imidazole on the market. The final Imidazole product is tested in our labs for elution of tagged protein from Ni columns.
