Description

MagStrep® Strep-Tactin®XT beads can be used for the purification of strep-tagged fusion proteins in batch or high-throughput format.For cell purification we offer specific magnetic beads with a smaller diameter (1µm) and for BioID targets we recommend our MagStrep® Strep-Tactin® beads.

MagStrep® Strep-Tactin®XT beads 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.

The beads can be easily and swiftly separated with a magnetic separator. This eliminates the need for centrifugation and reduces the risk of disturbing the pellet or loss of beads within the wash step to zero. The elution of target proteins or complexes can be triggered under mild conditions with the biotin-containing Buffer BXT or under denaturing conditions by boiling in SDS gel loading buffer.
