Invitrogen™ Dynabeads™ MyOne™ Streptavidin T1
Description
Includes
Supplied in PBS, pH 7.4 with 0.1% BSA and 0.02% NaN3 added as preservatives.
Dynabeads MyOne Streptavidin T1 beads are 1-μm monosized, monodispersed, superparamagnetic beads covalently coupled to streptavidin and intended for use in the isolation and handling of biotinylated nucleic acids, antibodies, and other biotinylated ligands. Their small but uniform size presents a high surface area per mg of beads and a correspondingly high capacity for the target ligand, while the high iron content ensures an efficient magnetic pull. These features, along with a slow sedimentation rate during incubation, contribute to a gentle and rapid magnetic separation. Excellent dispersion abilities and the lack of magnetic remanence make Dynabeads streptavidin products ideal for manual and automated protocols, including microfluidic system protocols.
Benefits of Dynabeads MyOne Streptavidin T1 beads include:
• Performance—high sensitivity and reproducibility secure consistent results
• Efficiency—fast binding kinetics and high binding capacity
• Flexibility—flexible protocols with gentle and efficient liquid-phase reaction kinetics
• Automation ready—easy automation for high-throughput needs on the Kingfisher Purification System
Consistency and reproducibility
The monolayer of streptavidin leaves most biotin-binding sites available for the binding of biotin and biotinylated ligands. The specific and defined surface allows for efficient capture, separation, and downstream handling. In addition, the low size distribution (<5%) of the monosized beads and the streptavidin monolayer ensure negligible leakage, providing batch consistency and reproducibility of results.
High binding capacity
The size of the molecule and the biotinylation procedure will affect the binding capacity. The capacity also depends on steric availability and charge interaction between bead and molecule and between molecules. With two or three biotin binding sites available for each streptavidin molecule on the surface of the bead after immobilization, one mg of Dynabeads MyOne Streptavidin T1 typically binds:
• 950–1,500 pmol free biotin
• ∼20 μg biotinylated IgG
• ∼400 pmol biotinylated peptides
• ∼20 μg biotinylated dsDNA
• ∼400 pmol biotinylated ss-oligonucleotides
Applications
Thermo Fisher streptavidin-coupled Dynabeads magnetic beads have been used and cited for a wide variety of applications. Although the beads can be used to isolate any biotinylated targets, these hydrophobic beads are particularly well suited for immunoassays, protein purification, cell isolation, phage display, and biopanning.
Automation ready with the KingFisher Purification System
The 1-μm magnetic beads are ideal for high-throughput enrichment. This process can be automated using any of our KingFisher Sample Purification Systems or liquid handlers.
