PureCube Zn-NTA Agarose
Protein Purification Protein Purification Reagents

PureCube Zn-NTA agarose resins are small agarose resin beads with a diameter of 40 µm. They are used for the purification of active His-tagged proteins from cells and the enrichment of Zinc-Binding proteins like Zinc-fingers.


  • Usage: Specific binding and purification of 6× His-tagged proteins, Binding of Zinc-binding proteins
  • Specificity: Affinity to His-tagged proteins, Affinity to Zinc-finger proteins
  • Binding capacity: >50 mg/ml
  • Bead ligand: Zn-NTA
  • Bead size: 40 μm
  • Filling quantity: Delivered as a 50% suspension
  • Metal ion capacity: >15 µeqv Zn²⁺/ml
  • pH stability: 2 to 14
  • Other stabilities: 100% methanol, 100% ethanol, 8 M urea, 6 M guanidinium hydrochloride, 30% (v/v) acetonitrile


Our year-long experience in manufacturing agarose resin led to the high yield of 50 mg protein per ml resin, which is leading in the market compared to other Zn-NTA suppliers. PureCube Zn-NTA resins are suited for batch spin columns and FPLC. Their small diameter provides them with great mechanical stability.
