Strep-Tactin® Superflow® high capacity is a resin for purification of strep-tagged proteins <90 kDa via affinity chromatography. The product is optimized for column-based use and suitable for HPLC/FPLC. It consists out of highly cross-linked agarose beads that are coupled to Strep-Tactin®, which is a streptavidin variant. Strep-Tactin® binds to proteins that were fused to a Strep-tag®II or a Twin-Strep-tag®, enabling a straightforward purification of tagged proteins from mixed samples, reaching a purity of >95%. Due to the targeted elution, tedious titration steps are not necessary. In addition, regeneration allows for multiple use of the resin.

In comparison to Strep-Tactin® Superflow, the high capacity version has a higher density of Strep-Tactin®, making it suitable for highly expressed proteins. This resin is also an alternative for proteins that are difficult to elute from our Strep-Tactin®XT 4Flow® resins.

Please note that biotinylated proteins also bind to Strep-Tactin® Superflow® high capacity. If biotinylated proteins are expected, use BioLock.  Furthermore, this resin is a 50% suspension, so for packing e.g. a 1 ml gravity column, 2 ml of resin is required.
