Nickel Nitrilotriacetic Acid Sensor Chip
SKU / Part #: 13206063This surface is used to capture histidine-tagged molecules such as recombinant proteins. The captured molecule is oriented well on the surface as the ligand is captured directly at the histidine tag via Ni²+/NTA chelation. The surface is easily regenerated with an injection of imidazole or EDTA to remove the metal ions and the captured ligand.
Here are the protocols for this sensor chip:
