Features and Benefits

  • A complex of three NTA groups ensures high-affinity binding of His-tags
  • Binding affinity is approximately four orders of magnitude higher than monovalent metal ion chelators
  • Protein binding is stochiometric
  • tris-NTA is available as amino-group or biotin conjugates
