The Protein A and Protein A/G antibody purification magnetic bead series use protein coupling technology to covalently immobilize Protein A and Protein A/G onto NHS-activated superparamagnetic microspheres. These products feature high antibody binding capacity, low non-specific protein adsorption, and uniform elution conditions, enabling isolation of antibodies with over 90% purity from serum samples in a single purification step. The large specific surface area of the micrometer-sized beads significantly shortens the equilibrium time required for antibody-antigen adsorption, completing antibody binding within 15 minutes and the entire antibody purification process within 30 minutes. This antibody purification magnetic bead kit includes optimized pre-prepared buffers, providing optimal reaction conditions and enhancing the stability of antibody purification experiments.
Protein A antibody purification magnetic beads have a particle size of 2 μm and an antibody capacity of 1.4‒1.6 mg/mL for human IgG. Protein A/G antibody purification magnetic beads have a particle size of 2 μm and an antibody capacity of 1.8‒2.0 mg/mL for human IgG. They are widely used for antibody purification from samples such as plasma, ascites, and tissue culture supernatants, as well as for antibody immobilization and other related studies.

GST Fusion Protein Purification Magnetic Beads are a novel functionalized material designed for efficient and rapid purification of glutathione S-transferase (GST) fusion proteins. They enable one-step purification of high-purity target proteins directly from biological samples via magnetic separation, simplifying the purification process and allowing efficient GST fusion protein purification. Compared to traditional column chromatography methods, this approach eliminates the need for repeated high-speed centrifugation and membrane filtration of crude protein samples, requires no flow rate control, and avoids costly chromatography equipment. Specific binding of samples to magnetic beads, washing, and elution of target proteins are simple, fast, and easy to perform. With skilled operation, high-purity target proteins can be obtained within 1 hour, and high-throughput processing of large-scale samples can be easily achieved, saving time and cost for users. This product is suitable for the purification of glutathione S-transferase (GST) fusion proteins, glutathione transferase, and other proteins with affinity for glutathione.

Histidine-Tagged Protein Purification Magnetic Beads are superparamagnetic and are a novel functionalized material designed for efficient purification of histidine-tagged proteins. They enable one-step purification of high-purity target proteins directly from biological samples via magnetic separation, simplifying the purification process and allowing efficient purification of histidine-tagged proteins. Compared to traditional chromatography using metal chelate agarose pre-packed columns, this approach eliminates the need for repeated high-speed centrifugation and membrane filtration of samples, requires no flow rate control, and avoids costly chromatography equipment. Specific binding of samples to magnetic beads, washing, and elution of target proteins are simple, fast, and easy to perform. With skilled operation, high-purity target proteins can be obtained within 1 hour, and high-throughput processing of large-scale samples can be easily achieved, saving time and cost for researchers.
This product series includes both nickel and cobalt ion chelating magnetic beads, which differ in target protein binding capacity and non-specific adsorption. Users can select the appropriate metal ion chelating magnetic beads based on the binding performance of the target protein to different metals and the desired yield and purity.
