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®) target proteins.
The binding affinity is in the range of antibody based immobilization system, but more economic and straight-forward to use.
New applications of the Strep-tag® system and key features
|New applications:||Excellent performance:|
Due to the high binding affinity of Strep-Tactin®XT with Twin-Strep-tag® in the low pM range, it is highly suitable for assays like SPR (surface plasmon resonance).
