New Sera-Mag® SpeedBeads™ Magnetic Protein A/G Particles

Thermo Fisher Scientific Inc., the world leader in serving science, today announced the development of their new Thermo Scientific Sera-Mag SpeedBeads Magnetic Protein A/G Particles designed to provide a fast and convenient method for both manual and automated magnetic isolation of IgA and IgG proteins using affinity binding.

Users can accomplish this in a single assay instead of running two separate assays, taking advantage of the affinity available with both proteins. The company will showcase the products at Thermo Scientific booth #1720 during Clinical Lab Expo at AACC 2011, being held July 26 – July 28, at the Georgia World Congress Center, Atlanta, Georgia.

These nominal 1 µm diameter, uniform, colloidally stable, monodispersed, non-porous superparamagnetic particles are able to isolate antibodies from serum, cell culture supernatant or ascites and for immunoprecipitation and co-immunoprecipitation of antigens from cell or tissue extracts. The unique, cauliflower-like surface of the particles also provides a much larger area for binding reactions than smooth surface particles.

Sera-Mag SpeedBeads Magnetic Protein A/G Particles contain two layers of magnetite locked in by polymer encapsulation. This results in much faster and complete separation in a magnetic field and it helps to increase throughput and improve precision in clinical diagnostic assays. It also enables faster movement through viscous solutions commonly found in molecular biology sample preparation applications.

Based on a patented (#5,648,124) core shell process and manufactured under strict quality and GMP controls in the Thermo Fisher Scientific medical device registered, ISO-13485 certified facility in Fremont, CA, the particles are supplied at 1% solids (10 mg/mL) in 0.05 % sodium azide, and are packaged in 1, 15 and 100 mL bottles.
