Immobilized metal-ion affinity chromatography (IMAC) resin

WB-IDANTA-productWorkBeads 40 NTA and WorkBeads 40 IDA

The WorkBeadsTM resins are based on nitrilotriacetic acid (NTA) and the iminodiacetic acid (IDA) chelating groups. The resins can easily be charged before use with a broad spectrum of divalent or trivalent transition metal ions, including Ni2+, Co2+, Cu2+, Zn2+, Ga3+ or Fe3+. They can then be used for 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. These resins can also be used for divalent metal ion removal.

  • Resin can be charged (or be pre-charged) with the metal ion of choice
  • High binding capacity and purity. Outstanding flow properties.
  • Reliable and reproducible results
