MagPlex®-Avidin Microspheres

Avidin-coupled, magnetic microspheres to characterize your peptide or protein of interest


MagPlex®-Avidin microspheres are avidin-coupled paramagnetic microparticles that have been color coded into 100 spectrally distinct sets or “regions.” Similar to an avidin-coated ELISA plate, when reacted with a biotinylated ligand, such as a peptide, each of these beads can be used as the substrate on which an assay can be performed.

Because each of the beads is uniquely color coded, they can be quickly distinguished by an xMAP® instrument, which allows interrogation of up to 100 different analytes, simultaneously, from a single sample. In addition, paramagnetic beads improve washing efficiency and eliminate the need for filter plates.


  • Avidin protein coated surface
  • 100 Regions available
  • Compatible with all xMAP® instruments
  • 1 mL vial size
  • 2.5 million bead/mL concentration


  • Near-covalent, biotin-binding chemistry
  • Ideal for coupling small molecules, like biotinylated peptides
  • Suitable for protein and immunogenicity applications
  • Convenient concentration for improved handling
  • Superparamagnetic
  • Improved washing efficiency
  • Expensive filter plates not needed
