Strep-Tactin® assay system

Strep-Tactin® coated microplates

allow the selective capture of Strep-tag®II or Twin-Strep-tag® fusion proteins from complex mixtures of molecules. The biomolecules are presented to interaction partners in a uniform manner which results in reliable and reproducible assay formats.

A comparison of immobilisation efficiency of Strep-Tactin®XT and Strep-Tactin® for Strep-tag®II and Twin-Strep-tag® fusion proteins can be found here.
