The Pierce™ Protein A/G Magnetic Beads are designed for efficient, high-yield immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and antibody purification protocols. Coated with a recombinant fusion of Protein A and Protein G, these 1 μm magnetic beads provide a wide IgG-binding spectrum, enabling robust capture of antibodies from multiple species and isotypes. Their compatibility with manual and automated workflows makes them ideal for high-throughput screening and reproducible small-scale experiments.
Key Features and Benefits
- High Binding Capacity – Offers nearly 4x more antibody-binding capacity than conventional magnetic beads
- Wide IgG Specificity – Combines Fc-binding domains from both Protein A and Protein G for broader species/isotype coverage
- Low Background – Pre-blocked surface minimizes non-specific binding for cleaner eluates
- Crosslinking-Compatible – Enables antibody immobilization to prevent IgG contamination in IP eluates
- Automation-Ready – Compatible with Thermo Scientific™ KingFisher™ Instruments and other robotic systems
- Efficient Magnetic Handling – Ensures fast separation, minimal bead loss, and reproducible performance
Applications
- Immunoprecipitation (IP) and co-immunoprecipitation (Co-IP)
- Antibody purification
- Protein complex isolation for downstream analysis (e.g., SDS-PAGE, western blot)
- Pre-clearing of lysates
- High-throughput magnetic bead workflows
