Imidazole (1,3-Diazo-2,4-cyclopentadiene; 1,3-Diazacyclopenta-2,4-diene; 1,3-diazole)
|Biochemicals||Storage: 4°CShipping: RT|
Imidazole can be used for the elution of histidine containing proteins from divalent cation resins.
Imidazole can be used to prepare buffers in the pH range of 6.2-7.8 at 25°C. It is also a chelator for the binding of various divalent cations.
The logs of the binding constants for various divalent cations are below:
Divalent Cation Log binding constant
Colorless, clear, complete
