MV3000 - Streptavidin - Protein Conjugated Magnetic Beads - Magnetic Beads (50nm-4.5μm) - By Products Type
Contact: 858-689-8808



These are streptavidin conjugated Mono Mag beads with diameter of 3 µm. 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. Their specific and defined surface allow for efficient capture, separation, and downstream handling.


  • Better or comparable performance with Dynabeads® M-280 Streptavidin and Dynabeads® M-270 Streptavidin  
  • Narrow size distribution, CV≤5%
  • Significant low non-specific binding to proteins and nucleic acid
  • No iron exposure to ensure lowest autosignal, particularly with respect to chemiluminescence
  • Easily adapted to automated processes.
  • Compatible with PCR reaction
