NHS magnetic beads are superparamagnetic particles featuring activated N-Hydroxysuccinimide groups on their surface. These groups enable direct covalent binding with primary amines on target ligands, forming stable amide linkages without requiring additional activation steps.

• Simplified Process: Direct covalent coupling without activation steps using EDC/NHS or glutaraldehyde
• High Efficiency: Achieves up to 90% bio-ligand coupling efficiency with superior binding capacity
• Rapid Coupling: Complete bio-ligand coupling in just 1-2 hours
• Mild Conditions: Room temperature or 4°C coupling with pH range of 5-9
• Exceptional Stability: Forms stable amide bonds preventing ligand detachment
• Biocompatible: Natural hydrophilic agarose substrate minimizes non-specific adsorption

BeaverBeads™ Mag NHS: Polymer-based solid microspheres (2 μm) for analytical applications including in vitro diagnostics, microbiological testing, and immunoprecipitation.

BeaverBeads™ Magrose NHS: Porous agarose microspheres (30-100 μm) with enhanced surface area for separation and purification applications including protein and antibody isolation.

Coupling must be performed in amino-free buffer solvents. Compatible with both manual operation and automated systems for high-throughput applications.
