China GSBIO Magnetic Solid-Phase Extraction (M-SPE) Beads
Our GSBIO Solid Phase Extraction Magnetic (M-SPE) Microspheres are products that integrate two major technological platforms: solid-phase extraction technology and magnetic separation technology. This product series not only achieves the performance of traditional fillers but also incorporates magnetic functionality. It simplifies the complex operations associated with conventional column-based separation by enabling magnetic separation, thereby overcoming a range of drawbacks inherent in traditional solid-phase extraction. This advancement allows for high-throughput, automated sample pretreatment.
The series of magnetic microspheres is divided into two main categories: C18 hydrophobic magnetic beads and HLB hydrophilic-lipophilic balanced magnetic beads.

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.

China GSBIO Nucleic Acid Extraction Magnetic Beads
Our GSBIO Nucleic Acid Extraction Magnetic Beads are magnetic microspheres with a core-shell structure, featuring superparamagnetic Fe3O4 as the core and abundant -OH or -COOH functional groups on the surface. This structure endows them with superparamagnetism, high specific surface area, excellent biocompatibility, and ease of surface functionalization. They are widely used in fields such as biomedicine, chemical analysis, and materials science.
· Fast & Efficient: Superparamagnetic properties enable rapid magnetic response (<30 seconds).
· High Binding Capacity: Large surface area maximizes nucleic acid yield.
· Reliable & Consistent: High batch-to-batch reproducibility.
· Ready-to-Use: Supplied as a stable aqueous suspension.
