Dialysis to remove imidazole

WebDialyze against the Dialysis Buffer at 4 o C overnight (about 16 hrs). Dialysis is to remove imidazole or glutathione if Ni or glutathione column is used to remove the cleaved tag or TurboTEV Protease after cleavage. If desired, the target protein pool can be buffer exchanged first before TurboTEV cleavage. Removal of TurboTEV Protease WebI understand that the protein dialysis process helps remove imidazole but why is it necessary to remove the imidazole from the protein sample after His-tag purification? Does it depend on the application? If I were to purify a his tagged protease enzyme whose catalytic mechanism involves a metal, protein dialysis is necessary.
