Sera-Mag SpeedBeads Protein A/G Magnetic Particles enable magnetic isolation of IgA and IgG proteins in a single isolation. Sera-Mag SpeedBeads Protein A/G Magnetic Particles provide a fast and convenient method for manual and automated magnetic isolation of affinity bound antibodies or antigens to Protein A/G. These particles can be used for isolating antibodies from serum, cell culture supernatants, or ascites, and for immunoprecipitation and co-immunoprecipitation of antigens from cell or tissue extracts.

• Manual and automated magnetic isolation of IgA and IgG proteins is accomplished in a single isolation instead of running two separate isolations
• Protein A/G binding sites allows use of a broad range of antibody species and sub-classes
• Low non-specific binding for fast and clean purification
• Fast reaction kinetics increases throughput and precision, and also enables faster movement through viscous solutions
• Unique cauliflower-like surface provides increased area for binding reactions compared to smooth surface particles
• Uniform, nominal 1 μm diameter provides excellent lot-to-lot reproducibility
