Datasheet Ni-NTA Resin allows rapid affinity purification of His-tagged proteins. His-tagged proteins bind to Ni2+ cations, which are immobilized on the Ni-NTA resin by 4 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. Specifications:

| Directions for use | Preparing the Ni-NTA purification column:
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-NTA resin:
