Ni-IDA Resin allows rapid affinity purification of His-tagged proteins. His-tagged proteins bind to Ni
2+ cations, which are immobilized on the Ni-IDA resin by 3 metal-chelating sites. After unbound proteins are washed away, the target proteins are recovered by gradient elution. It is suitable for both native and denatured protein purification.

Directions for use |
Preparing the Ni-IDA purification column: - Thoroughly resuspend the Ni-IDA resin to achieve a homogeneous suspension of the resin in 20% ethanol storage buffer.
- Immediately transfer the resin into a purification column. Ensure that the bottom of the column is plugged with a stopper. Close the value of the column and allow the resin to settle.
- Equilibrate the column with 5-10 bed volume of equilibration buffer.
Preparing samples: To avoid blocking the column, samples should be centrifuged and filtered through a 0.45 µm filter before loading. Loading samples and washing: Load samples and wash with 5-10 bed volume of equilibration buffer, and collect the flow-through in a tube Elute: Elute proteins with imidazole or low pH buffer. Regeneration of Ni-IDA resin: - Wash the column/resin with:
- 5 bed volume of deionised water.
- 3 bed volume of 2% SDS.
- 1 bed volume of 25% ethanol.
- 1 bed volume of 50% ethanol.
- 1 bed volume of 75% ethanol.
- 5 bed volume of 100% ethanol.
- 1 bed volume of 75% ethanol.
- 1 bed volume of 50% ethanol.
- 1 bed volume of 25% ethanol.
- 1 bed volume of deionised water.
- 5 bed volume of 100 mM EDTA, pH 8.0.
- 10 bed volume of deionised water.
- 5 bed volume of 100 mM NiSO4.
- Store the column/resin in 20% ethanol.
