Streptavidin Magnetic Beads For Biomarker Discovery And Therapeutic Development

Rebeads® Mag SA is manufactured by covalently conjugating recombinant neutral streptavidin onto uniform magnetic microspheres using oriented immobilization, forming a single‑molecule layer.It captures biotinylated biomolecules, ligands and targets through the streptavidin‑biotin system, enabling target sequence enrichment for NGS library preparation.

Process Flow

• High Binding Capacity: Higher binding capacity than comparable products; small particle size with minimal non-specific adsorption.
• Strong Specificity: Specifically binds biotinylated ligands including antibodies, nucleic acids, proteins and peptides, delivering high-purity products.
• Fast Binding: Rapid binding to biotinylated molecules with short incubation time, improving overall workflow efficiency.
• Easy to Use: Suitable for both manual processing of small-volume samples and automated systems for high-throughput screening.
