Description
The Strep-Tactin®XT 4Flow® high capacity gravity flow columns can be used for the purification of proteins that have been tagged with Strep-tag®II or Twin-Strep-tag®. These fusion proteins bind very specifically to the high affinity Strep-Tactin®XT ligand resulting in highly pure target proteins (>95%). It is recommended for challenging and low abundant proteins because of its stability and low agarose concentration. For proteins with increased affinity, like multimeric proteins, Strep-Tactin® resins for easier elution are recommended.

FAQ
Can I get the datasheet for the Strep-Tactin®XT 4Flow® high capacity resin?
Yes. Just click here to download it as a PDF File.
Is Strep-Tactin® the same as Streptavidin?
No, they are not. Strep-Tactin® is a bioengineered protein, originally based on Streptavidin. However, Strep-Tactin® cannot bind to biotin, while Streptavidin cannot bind to the Strep-tag.
