Beads & Microspheres

TargetMol Mag Beads Dextran are superparamagnetic iron oxide particles with an average particle size between 13-15 nm, which are coated with dextran molecules. The dextran shell layer on the surface of the particles makes them biocompatible and suitable for a variety of biological applications. The surface functional group is a carboxyl group, which enables the beads to efficiently bind to various biomolecules (e.g., proteins, antibodies, and enzymes) via covalent bonding, and is widely used in biological separation, purification, and detection. This coating not only enhances the stability of the particles, but also provides additional functionality.

The streptavidin (SA)/biotin interaction, known for its high binding affinity (K = 10^-15), has been widely applied in the biological field. TargetMol Mag Beads Streptavidin covalently connects SA to the beads surface through protein-protein coupling method. This enables efficient binding of biotinylated antibodies, nucleic acids, and proteins. The product combines superparamagnetic advantages with unique features including uniform size and regular morphology, facilitating the rapid capture of target molecules and magnetic separation. This product can be used with automated equipment for high-throughput technology.

TargetMol Mag Beads NHS (300 nm) are modified with NHS groups on the surface to form stable peptide bonds with proteins and other molecules with primary amine groups for affinity purification of antibodies, antigens and other biomolecules. In contrast to traditional carboxyl and amino magnetic beads, magnetic beads with NHS groups on the surface do not require prior activation with EDC/NHS or glutaraldehyde. The biologic ligands containing primary amines can be covalently coupled to the beads by simply dissolving the biologic ligands in coupling buffer, and then mixing the proteins with the NHS beads for 1~2 h at room temperature. The bead coupling process must be carried out in a buffered solvent that does not contain any amines. The beads are separated from the solvent manually using a magnetic separation rack. Automated equipment is also available and is suitable for multi-sample screening.
