Product Description
Direct Covalent Coupling Magnetic Beads
Agarose NHS Activated Magnetic Beads with 20% volume ratio in 5 mL format, featuring pre-activated NHS groups for immediate protein conjugation without additional activation steps.
Product Overview
BeaverBeads™ Mag NHS and BeaverBeads™ Magrose NHS are spherical magnetic beads modified with NHS groups that form stable peptide bonds with proteins and other molecules containing primary amine groups. These beads are designed for affinity purification and assay detection of antibodies, antigens, and various biomolecules.

Key Advantages
- Simple operation - No activation required, direct covalent coupling with biological ligands
- High efficiency - Up to 90% bio-ligand coupling efficiency 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 detachment
- Excellent biocompatibility - Minimized non-specific adsorption for cleaner results
Application Benefits
Compared to traditional beads with carboxyl or amino groups, these NHS-activated beads eliminate the need for EDC/NHS or glutaraldehyde pre-activation. Simply mix the protein solution containing primary amino groups with Mag NHS beads at room temperature for 1-2 hours to achieve ligand attachment.
