Description

Description générale

Imidazole is a buffering agent employed in various research applications, with a pH 9 -11, it is often used to maintain a stable pH for protein samples. Imidazole is a heterocyclic compound with a five-membered planar ring that is amphoteric, highly polar, and commonly used for affinity chromatography. Its ability to bind to metal ions makes it particularly useful for purification and separation of proteins.

Application

Excellent pour les tampons compris dans la plage de pH 6,2-7,8

Imidazole is commonly used as a buffer component for purification of the histidine-tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).
