Provide total solutions for Life Science applications together with global partners. We are constantly striving to be more connected, forward-looking and customer-focused to deliver best results.
We are happy to announce the launch of a new and optimized version of our top selling magnetic beads.
The new MagStrep® Strep-Tactin®XT beads have catalog numbers 2-5090-002 and 2-5090-010
Researchers can expect the same high yield and purity of the product, therefore no adaptations to your current procedures are necessary. And as additional advantages: The new magnetic beads also come with a quicker protocol that will save around 30 minutes of lab work compared to other magnetic bead-based protein purification procedures.
Description
MagStrep Strep-Tactin®XT beads can be used for the purification of strep-tagged fusion proteins in batch in single or high-throughput format.For cell purification we offer specific magnetic beads with a smaller diameter (1µm) and for biotinylated proteins we recommend our MagStrep “type3” 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 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.
