Application

Imidazole can be used to prepare buffers in the pH range of 6.2-7.8 at 25°C. It is recommended as a component of a buffer for assay of horseradish peroxidase and as chelator for the binding of various divalent cations. Imidazole can be used for the elution of histidine containing proteins from divalent cation resins (Sigma P6611, HisSelect.-HC Nickel affinity gel) and can also be used in reverse staining of SDS-PAGE gels for detection of proteins.

Excellent for buffers in the range of pH 6.2-7.8
