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 system, but more economic and straight-forward to use.
|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).
Request unconjugated Strep-Tactin®XT using this form:
- Ready-to-use 96-well plates
- Minimal non-specific binding
- Minimal coefficients of variation
- High affinity (pM range)
- Reversibility maintaines upon addition of biotin
- Cost effective

|Strep-Tactin® XT coated microplate||1 plate||2-4101-001||USD 60.00|
Ready-to-use microplates (12 x 8-well strips) for diagnostic/assay applications, coated with Strep-Tactin® XT, a new Strep-Tactin variant with higher affinity for Strep-tag® II fusion proteins (nM affinity) and especially Twin-Strep-tag fusion proteins (pM affinity). Fusion proteins are selectively captured from complex mixtures and the biomolecules of interest are presented to interacting partners in a uniform manner which results in reliable and reproducible assays. The solid-phase, ...
