MagPlex®-Avidin Microspheres

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

Avidin-coupled Magnetic microspheres for characterizing the target peptide or protein


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
