Dynabeads are used on more than 25,000 routine IVD instruments worldwide and are known for exceptional reproducibility (both within and between batches) and automation ability. The strong binding affinity of streptavidin-biotin interaction (Kd=10-15) is used in vast number of applications.

  • Direct and fast isolation of any biotinylated molecule
  • Low-charged and neutral beads, optimal for binding of DNA fragments, proteins, peptides, and antibodies
  • Flexible protocols with gentle and efficient liquid-phase reaction kinetics
  • Biomagnetic protocols are easily adapted to automated platforms
  • High batch-to-batch reproducibility, securingconsistent results in application
  • Bead Diameter: 2.8 μm
  • Concentration: 10mg/mL
  • High throughput compatible
  • Sample Type: Any Sample Type

  • Diameter: 2.8°m, with monolayer, not a multilayer, of recombinant streptavidin covalently coupled to surface and further blocked with BSA
  • Show rapid liquid-phase reaction kinetics.
  • Key applications: Preparing 2 to 5kb samples for mate pair library sequencing, isolation of RNA and DNA binding proteins, immobilization of large DNA fragments, purifying sequencing products, specific capture of nucleic acids
  • Dynabeads™ are used on more than 25,000 routine IVD instruments worldwide
