A chromatography resin for purification of recombinant proteins tagged with Strep-tag II and Twin-Strep-tag. These proteins bind very specifically to the immobilised Strep-Tactin XT ligand giving highly pure target protein.

• Highly pure Strep-tag II and Twin-Strep-tag recombinant proteins
• Fast purifications with simple elution
• Physiological conditions and mild elution preserve target protein activity
• Fast and easy regeneration
• Compatible with a wide range of detergents, denaturants, and other additives

Strep-Tactin XT Sepharose contains the latest Strep-Tactin ligand, XT, which provides higher affinity, resulting in higher yields and lower loss of valuable target protein than with the predecessor product, StrepTactin sepharose high performance (HP). Strep-Tactin XT Sepharose also enables purification under denaturing conditions.
