Twin-Strep-tag® Capture Kit is intended for site-directed, reversible capture of Twin-Strep-tag® fusion proteins for biomolecular interaction analysis using surface plasmon resonance (SPR) devices. The kit provides Strep-Tactin®XT, SPR Immobilization Buffer, Regeneration Buffer and GFP-Twin-Strep-tag® as control protein. It enables the highly stable immobilization of the ligand based on the unique Strep-Tactin®XT:Twin-Strep-tag® technology, due to the pM affinity of Twin-Strep-tag® to Strep-Tactin®XT.
The key benefits are:
The use of unconjugated Strep-Tactin®XT protein requires a license that is provided with the purchase of the kit as limited use license.
