Magarose Beads have superparamagnetism and rapid magnetic responsiveness. Peptides, proteins, antibodies, oligomeric nucleotide biological ligands can be coupled to the surface of microspheres. Magarose Beads is an important carrier of the medical and molecular biology research tools.The particle size of Magarose Beads is about 30 to 100 µm and it is more suitable for biological examination and purification experiment. rProtein A/G Magarose Beads is an affinity chromatography Magnetic beads designed for easy, one-step binding of classes, subclasses and fragments of immunoglobulins from biological fluids and from cell culture media. The recombinant protein A/G ligand is coupled to Magnetic beads.
