- Simplified Protocol: No activation required - directly covalently couples with biological ligands
- High Efficiency: Achieves bio-ligand coupling efficiency exceeding 90%, significantly higher than carboxyl beads with superior binding capacity
- Rapid Processing: Complete bio-ligand coupling in 1-2 hours
- Mild Conditions: Room temperature or 4°C coupling with pH range of 5-9
- Exceptional Stability: Forms stable amide bonds to prevent ligand dissociation
- Superior Biocompatibility: Minimized nonspecific adsorption for cleaner results
These preactivated magnetic nanoparticles are ideal for affinity purification and assay detection of antibodies, antigens, and various biomolecules. The elimination of EDC/NHS or glutaraldehyde activation steps streamlines workflow while maintaining high performance standards required in research and diagnostic applications.
