Mag Beads COOH (3 μm)

Mag Beads COOH (3 μm) are high-quality Fe3O4 microspheres coated with carboxyl (-COOH) groups. These beads allow for rapid, efficient, sensitive, and specific covalent coupling of biomolecules—such as peptides, proteins, and oligonucleotides—to the microsphere surface under the action of specific chemical reagents like EDC. The resulting conjugates can be used in applications such as immunoprecipitation (IP), cell sorting, and DNA–protein interaction studies, making them valuable carrier tools in medical and molecular biology research. The shell of Mag Beads COOH (3 μm) is functionalized with carboxyl groups to reduce bead aggregation and sedimentation. Carboxyl magnetic beads exhibit acidity and are typically activated with EDC in acidic buffer systems. This product line is a water-based suspension of carboxyl-coated, superparamagnetic Fe3O4 microspheres. Manufactured using advanced technology, these beads combine magnetic cores with polymeric materials to form a novel class of functionalized magnetic microspheres.
