BabyBio Cu-NTA 1ml x2 45655122

BabyBio™ NTA columns for Immobilized Metal Ion Affinity Chromatography (IMAC) are ready-to-use for quick and easy purification of polyhistidine-tagged (His-tagged) proteins and other proteins with an affinity for metal ions. The columns are prepacked with pre-charged or uncharged WorkBeads™ 40 NTA resins. They are available in two-column sizes, 1 ml, and 5 ml. IMAC utilizes the affinity of histidine, cysteine, and tryptophan amino acid side chains on the protein surface for binding to transition metal ions, such as Ni2+, Co2+, Cu2+, and Zn2+, which are immobilized via the metal chelating ligand on the chromatography resin.

• High binding capacity and purity
• Pre-charged resins with different metal ions for convenient screening for optimal purity
• Uncharged resins can be charged with the metal ion of choice
• Prepacked ready-to-use columns for rapid and reliable results

Product

The BabyBio™ NTA resins are based on the nitrilotriacetic acid group (NTA) chelating group. The resin can easily be charged, before use, with a broad spectrum of divalent or trivalent transition metal ions, including Ni2+, Co2+, Cu2+ or Zn2+, Fe3+ or Ga3+.

They can then be used for the Immobilized Metal Ion Affinity Chromatography (IMAC) purification of His-tagged proteins or other proteins with an affinity for metal ions. The selectivity of the metal-charged resin depends on both the choice of ligand (NTA or IDA) and the metal ion used. The uncharged resins can also be used for divalent metal ion removal.
