Strep-Tactin® 4Flow®
Strep-Tactin® 4Flow® high capacity is a resin for purification of strep-tagged proteins via affinity chromatography. The product is optimized for column-based use and suitable for HPLC/FPLC. It consists out of 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.
