MonoMag Maleimide Beads

MonoMag Maleimide Beads are activated magnetic beads in lyophilized powder form. The maleimide activated surface allows covalent bond formation to antibodies, proteins, peptides or other biomolecules via thiol (SH) groups. Oligonucleotides, antibodies or other ligands with thiol groups can be easily coupled to the beads. Attribute to their uniform size, narrow size distribution, short magnetic separation time, and unique surface coating, MonoMag Maleimide Beads exhibit rapid binding chemistry and low non-specific binding of protein or nucleic acids.


  • Narrow size distribution, CV≤5%; Significantly low non-specific binding to proteins and nucleic acid
  • High binding capacity
  • Immediate and gentle coupling at room temperature and neutral to low pH
  • No iron exposure to ensure lowest autosignal, particularly with respect to chemiluminescence
  • Easy to use


  • Immunoassay
  • Immunoprecipitation
  • Nucleic acid hybridization
  • Western blot
  • Cell separation
