China GSBIO Immunomagnetic Beads

Our GSBIO Immunomagnetic Beads are magnetic microspheres composed of a magnetic core, a polymer coating, and specific functional groups on the surface. The magnetic core is typically made of iron oxide (Fe₃O₄), which imparts superparamagnetic properties to the beads. The polymer coating (such as polystyrene or silica) provides excellent dispersibility and serves as a platform for chemical modification. The functional groups act as active sites for specific binding with target biomolecules. This product series is primarily used for the immobilization of biomolecules such as antibodies, proteins, peptides, and oligonucleotides. It is widely applied in immunoprecipitation, cell sorting, immunoassays, DNA-protein interaction studies, drug screening, and other related fields.
