MagStrep® Strep-Tactin®XT beads
Order number: 2-5090-002
Description
MagStrep® Strep-Tactin®XT beads can be used for the purification of strep-tagged fusion proteins in batch or high-throughput format. show low non-specific protein binding due to their agarose surface and high specificity of Strep-Tactin®XT towards Strep-tag. This results in outstanding target protein purity and makes the MagStrep® Strep-Tactin®XT beads the ideal tool for protein isolation and complex identification via pull-downs. MagStrep® Strep-Tactin®XT beads are suitable for fast small-scale purifications in reaction tubes as well as 96-well plates.

FAQ
Can I get the datasheet for the MagStrep® Strep-Tactin®XT beads?
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.
