Strep-Tactin®XT 4Flow® - Resin with enhanced properties

High-performance Strep-Tactin®XT 4Flow® replaces Strep-Tactin®XT Superflow®

Our powerful resins, Strep-Tactin®XT 4Flow® and Strep-Tactin®XT 4Flow® high capacity, replace Strep-Tactin®XT Superflow® as well as Strep-Tactin®XT Superflow® high capacity as of July 1st, 2021. In comparison to Strep-Tactin®XT Superflow® resins, Strep-Tactin®XT 4Flow® resins have improved and enhanced properties and are, therefore, our Strep-Tactin®XT resins for the future.

Strep-Tactin®XT 4Flow® and the high capacity variant are perfectly suitable for efficient protein purification independent from the protein class, including challenging proteins, low abundant proteins and especially large proteins. Furthermore, the broad pH stability enhanced the compatibility with different buffer compositions.
