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.
Isolate IgA and IgG Simultaneously
By taking advantage of the affinity provided by both Protein A and Protein G, Sera-Mag SpeedBeads Protein A/G Magnetic Particles are a flexible alternative to either Protein A or Protein G alone and can purify IgG from rabbit and mouse serum with higher yield and purity than Protein A and Protein G particles alone.
Sera-Mag SpeedBeads Respond Twice As Fast
The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. Two layers of magnetite are coated onto this core, resulting in faster magnetic response times, while the surface is modified with a proprietary method that minimizes non-specific binding of proteins. Protein A/G is then covalenty bound to the particle surface.
