Merck, 70666-5CN, Ni-NTA His•Bind® Resin

Ni-NTA His•Bind Resin is a high-performance Ni²⁺-charged agarose used for rapid one-step purification of proteins containing a His•Tag sequence by metal chelation chromatography. NTA chemistry minimizes metal leaching during purification and is compatible with up to 10 mM β-mercaptoethanol or 1 mM Tris(hydroxypropyl)phosphine (THP) for reduction of disulfide bonds. Ni-NTA His•Bind Resin has a binding capacity of 5–10 mg His•Tag fusion protein per ml resin. Supplied as a 50% slurry; the quantity/pack is based on the amount of the settled resin.
