Magnosphere™ Magnetic Beads

Magnetic beads are used for many different applications in the life sciences including immunoprecipitation, cell isolation, exosome analysis and more.  When compared with competitor products, Magnosphere™ magnetic beads have shown to have no iron oxide exposure and to have optimal performance in Chemiluminescence enzyme immunoassay.

Key Properties

  • Core shell structure and uniform particle diameter
  • Surface hydrophobic or hydrophilic property
  • Low iron exposure
  • Higher signal
  • Faster magnetic response
