DescriptionThermo Scientific Pierce Protein A/G Magnetic Beads are high-performance affinity particles for antibody purification and immunoprecipitation methods using manual or robotic magnetic separators. Features of Protein A/G Magnetic Beads: • High capacity—nearly four times higher binding capacity than typical magnetic beads from other suppliers, allowing the use of smaller amounts per experiment These magnetic beads are coated with genetically engineered Pierce Protein A/G, a recombinant fusion protein which combines the IgG binding domains of both Protein A and Protein G. This enables capture of antibodies from a wider range of species and isotypes than either protein alone. Using our crosslinker chemistry, you can immobilize an antibody onto the magnetic particle and prevent IgG contamination in your immunoprecipitated sample. These beads can be used both manually with a magnetic stand as well as with automated platforms such as the Thermo Scientific KingFisher Instruments. Applications: The recombinant Protein A/G that is immobilized onto the Pierce Magnetic Beads is a fusion of the IgG binding domains of both Protein A and Protein G. Protein A/G contains four Fc-binding domains from Protein A and two from Protein G, making it a convenient tool for investigating and purifying immunoglobulins. Thus, Pierce Magnetic Particles are not simply a mixed immobilization of separate Protein A and Protein G polypeptides, nor are they a mixture of Protein A magnetic beads and Protein G magnetic beads. |
