Add to Cart:
Magnetic silica beads are surface activated magnetic particles intended for covalent immobilization of proteins (e.g. antibodies, enzymes), peptides, nucleic acids or other molecules of interest. Different surface modifications and bead sizes allow for the selection of the optimal product for the application and molecule to be coupled. After the molecule of interest (ligand) is coupled to the magnetic particles, the resulting beads can be used in downstream applications such as detecting, enriching, or cleaving specific target molecules. The simple and efficient collection in magnetic fields allows for easy rinsing and removal of excess reagents and ligand after coupling. 

MD03004 beads consist of superparamagnetic silica particles with a carboxyl (S-COOH) modified surface. They are intended for carbodiimide coupling chemistry with NH2-containing molecules. These beads can be used to couple most proteins.


  • Ideal tool for carbodiimide coupling chemistry with NH2-containing molecules
  • Does not require columns or centrifugation steps
  • Suitable for high-throughput and automated applications
  • Concentration of 10mg/ml (beads/ml)


  • Carbodiimide coupling chemistry with NH2 containing molecules
  • Immobilization of proteins, peptides, antibodies, etc. 


  • Magnetic Silica Beads with carboxyl surface (S-COOH), 1μm bead size, 10ml
