Description

• Can be used for the purification of strep-tagged fusion proteins in batch in single or high-throughput format.
• 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 beads a perfect tool for the isolation of proteins or the identification of complexes via pull-downs, immunoprecipitation (IP), or co-immunoprecipitation (Co-IP).
• 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.
