SV0050 - Streptavidin - Protein Conjugated Magnetic Beads - Magnetic Beads (50nm-4.5μm) - By Products Type
Contact: 858-689-8808



These are streptavidin conjugated Super Mag beads with diameter of 50 nm. The magnetic beads are pre-blocked by a layer of BSA before a monolayer of recombinant streptavidin covalently coupled to the surface. The monolayer of streptavidin makes most of the biotin binding sites sterically available for binding of biotinylated nucleic acids, antibodies, or other biotinylated ligands and targets. The 50 nm Super Mag Streptavidin Beads have high capacity, efficient magnetic pull, and no sedimentation during incubation.


  • High binding capacity
  • Significant low non-specific binding to proteins and nucleic acid
  • Can be separated by both permanent magnets and high gradient magnetic column due to high percentage of magnetic content


Ideal for cell separation and assay development. Low non-specific binding of proteins and nucleic acids.

Binding capacity:

  • >20 µg biotinylated IgG/mg beads
