描述 Thermo 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
• Low non-specific binding—stable, pre-blocked beads provide clean purification products (e.g., antigen eluted in IP with antibody is devoid of contaminating proteins from complex IP matrix)
• Flexibility—convenience of IgG binding domains of both Protein A and Protein G on one bead
• Compatibility—beads are compatible with manual and automated applications (e.g., Thermo Scientific KingFisher Instruments)
• Assay consistency—magnetic beads eliminate resin loss and provide for more efficient separation of solutions than traditional IP methods that use only microcentrifuge tubes

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:
• IP and Co-IP experiments (see complete kit)
• Immunoprecipitation for analysis in non-reducing conditions
• Antibody purification

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.
