蛋白质提炼用树脂 - Immobilized Metal

WorkBeads™ 40 Co-NTA

Agarose-based resin for chromatography

 

WorkBeads™ 40 NTA resins are based on the nitrilotriacetic acid (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+ and Zn2+, Ga3+ or Fe3+.
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.
, which are immobilized via a metal chelating ligand on the chromatography resin.

• Resin charged (or pre-charged) with the metal ion of choice
• High binding capacity and purity. Outstanding flow properties.
• Reliable and reproducible results
• Prepacked ready-to-use columns for rapid and reliable results - see BabyBio IMAC page

 

 

Product
The WorkBeads™ NTA resins are based on the nitrilotriacetic acid (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.​

1. The median particle size of the cumulative volume distribution.
2. Metal ion capacity is determined by frontal analysis at 50% breakthrough using cupper solution.
3. The binding capacity is determined using a BabyBio Ni-NTA 1 ml. The binding capacity is dependent on the size of the target protein, and on the competition of impurities.​
