Ocean NanoTech’s streptavidin coated magnetic beads offer easy affinity isolation or handling of biotinylated nucleic acids, antibodies, or other biotinylated ligands and targets without columns or centrifugation. Our streptavidin coated magnetic beads are uniform and superparamagnetic beads with a monolayer of recombinant streptavidin covalently coupled to the surface. With excellent size control techniques, the size range we offer is from 50 nm to 1 µm. The high-affinity interaction between streptavidin and biotin (Kd=10-15) is used in a vast number of applications.

  • High capacity: Equivalent or higher binding capacity than other suppliers
  • Low nonspecific binding: stable, pre-blocked beads provide clean purification products without interference from the non-specific binding of complex samples
  • Size flexibility: streptavidin coated magnetic beads offer sizes from 50 nm to 1 µm
