原装现货|DYNABEADS MYONE STREPTAVIDIN
描述:
Streptavidin-coupled Dynabeads® is the gold standard for isolation and handling of biotinylated nucleic acids, antibodies or other biotinylated ligands and targets. The very high binding affinity of the streptavidin-biotin interaction (Kd=10^-15) is utilized in a vast number of applications.
These uniform and superparamagnetic beads are 1 µm in diameter, with a monolayer – not a multilayer - of recombinant streptavidin covalently coupled to the surface and further blocked with BSA. The monolayer of streptavidin leaves the vast majority of the biotin binding sites sterically available for binding, not only of free biotin, but also for binding of biotinylated ligands/targets. The beads show rapid liquid-phase reaction kinetics. Their specific and defined surface allow for efficient capture, separation and downstream handling. The streptavidin monolayer ensures negligible leakage, and the lack of excess adsorbed streptavidin ensures batch consistency and reproducibility of your results.
