Strep-Tactin® Superflow® high capacity column
Please note that this product will be discontinued and replaced by Strep-Tactin® 4Flow® high capacity column. Strep-Tactin® Superflow® high capacity column will still be available until 31st October 2024 or as long as stock lasts.
Check out the features of the new resin here.
Strep-Tactin® Superflow® high capacity columns are ready-to-use for purifying strep-tagged proteins below 90 kDa via affinity chromatography. These gravity flow columns contain a highly cross-linked agarose coated with streptavidin variant Strep-Tactin®, which captures proteins fused to a Strep-tag®II or a Twin-Strep-tag®. A straightforward purification principle results into a highly pure (>95%) protein preparation. After regeneration, the columns can be used multiple times.
Please note that biotinylated proteins also bind to Strep-Tactin® Superflow® high capacity. If biotinylated proteins are expected, use BioLock. Furthermore, if large (sample and/or buffer) volumes have to be applied, we recommend our WET FRED system.
