BeaverBeads ™ Mag NHS and BeaverBeads ™ Magrose NHS are superparamagnetic beads with activated groups of N_Hydroxysuccinimide on the surface, which can react with primary amines on desired ligands and bind them covalently with amide linkage to the beads. The ligand can be various molecules including antigen, antibody and other proteins. Compared with the traditional carboxyl, amino magnetic beads, the NHS group of magnetic beads don’t need to activate EDC/NHS or Glutaraldehyde, simply dissolving the amino-containing bio-ligand in the coupling buffer, at room temperature, mixing with proteins and the NHS magnetic beads for only 1-2 hours, the bio-ligand can be coupled to the magnetic beads.

  • Simple, without activation, can be directly covalently coupled with the biological ligand;

  • Efficient, bio-ligand coupling efficiency of up to 90% or more, much higher than the carboxyl beads, while the ligand with a higher binding capacity;

  • Fast, 1 ~ 2h to complete the bio-ligand coupling;

  • Mild, room temperature or 4 ℃ coupling, coupling system pH 5 ~ 9;

  • Stable, the formation of a stable amide bond, to prevent the ligand off.

  • Good biocompatibility, reduced nonspecific adsorption.


Applicable scope
It is suitable for covalent coupling of biomolecules such as protein, antibody, enzyme, polypeptide and nucleic acid containing primary amino group.
