Immobilization with Strep-Tactin®XT:Twin-Strep-tag®


Due to the extra tight binding affinity of Strep-Tactin®XT to Twin-Strep-tag®, the system is highly suitable for efficient immobilization of Twin-Strep-tag® (and Strep-tag®II) fusion proteins.

The binding affinity is in the range of antibody based immobilization systems, but more economic and straight-forward to use.


Key benefits of Strep-Tactin®XT and Twin-Strep-tag® for immobilization experiments

  • High affinity in pM range (T1/2 = 13 h)
  • Reversibility due to addition of Biotin
  • Minimal non-specific binding
