HisTrap™ FF columns are designed for simple, one-step purification and scaling up purification of histidine-tagged proteins. The columns are pre-packed with Ni Sepharose™ 6 Fast Flow.

• High binding capacity, approx. 40 mg/ml medium
• Negligible leakage of Ni²⁺
• Prepacked columns
• Compatible with a wide range of reducing agents, detergents, denaturants, and additives

This chelating ligand is charged with Ni²⁺ ions, the first-choice metal ion for purifying most histidine-tagged proteins. The negligible leakage of Ni²⁺ ions from the matrix ensures reliable capture of histidine-tagged proteins in repeated IMAC purifications. The high flow rates made possible by the Ni Sepharose 6 Fast Flow matrix make HisTrap FF columns well suited for small scale-up. Capacity can be increased by connecting columns in series. HiTrap IMAC FF is the product of choice when charging the medium with different metal ions for optimization of purification protocols.

Ni Sepharose 6 Fast Flow consists of 90 µm beads of highly cross-linked agarose, to which a chelating ligand has been immobilized. Prepacked columns offer reliable and convenient time-saving purification of histidinetagged recombinant proteins.
