Strep-Tactin®XT: Xtra Tight (pM affinity) immobilization of Twin-Strep-tag® fusion proteins
Ready-to-use microplates (12 x 8-well strips) for diagnostic/assay applications, coated with Strep-Tactin®XT, a further developed Strep-Tactin® variant with higher affinity for Strep-tag®II fusion proteins (binding affinity in nM range) and especially Twin-Strep-tag® fusion proteins (binding affinity in pM range). They are selectively captured from complex mixtures and the biomolecules of interest are presented to interaction partners in a uniform manner which results in reliable and reproducible assays. The solid-phase, multi-well format for convenient assays and high throughput screenings is compatible with standard multichannel pipettes and automated plate washers and plate readers.
Note that the bound fusion protein can still be eluted from the microplate.
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).

Ready-to-use Strep-Tactin® coated 8-well strips provide the power of our Strep-tag® system in a solid-phase, multi-well format for convenient assays and high throughput screenings of biomolecules tagged with Strep-tag®II. The strips are supplied framed in sets of 12, resulting in a 96-well configuration compatible with standard multichannel pipettes and automated plate washers and plate readers. The biomolecules are presented to interacting partners in a uniform manner, which results in reliable and reproducible assay formats.
High-affinity Strep-tag®II/Twin-Strep-tag® specific monoclonal antibody for capturing Strep-tag® fusion proteins on solid phases
• optimal for capturing Strep-tag® fusion proteins on solid phases (e.g. Biacore chips1)
• high affinity both with C- and N-terminal Strep-tag® fusion, provided the Strep-tag® is N-terminally extended by a SerAla-linker

StrepMAB-Immo is a murine, high-affinity Strep-tag®II specific monoclonal antibody which is especially suited for stable, mild and oriented capturing of Strep-tag®II fusion proteins on solid phases. To realize this, the antibody can be immobilized on e.g. microplates, Biacore CM5 sensor chips or other biochips. The nearly irreversible binding is achieved both for fusion proteins carrying a C- or N- terminal Strep-tag®. The Strep-tag® must be N-terminally extended by a SerAla linker (recombinant protein - SA-WSHPQFEK or SA-WSHPQFEK - recombinant protein).
