Strep-Tactin® 4Flow®
Strep-Tactin®XT 4Flow® columns contain a 4% agarose coupled with the streptavidin variant Strep-Tactin®XT. Due to the broad pH compatibility, excellent pressure stability, outstanding target purity (> 95%), and highest binding affinity, the resin is recommended for all protein classes, especially for low abundant or challenging proteins. The low concentrated agarose enables the simple attachment of larger proteins to the stationary phase, making it particularly suitable for purification of high-molecular-weight targets. In addition, Strep-Tactin®XT 4Flow® allows the application of denaturing agents such as urea. In addition, a further increase in protein yield can be achieved through the high capacity variant of Strep-Tactin®XT 4Flow®.
