Sera-Mag SpeedBeads Amine-Blocked Particles combine a fast magnetic response time and high binding capacity with a large surface area, high sensitivity, stability, physical integrity, and fast reaction kinetics.
  • Non-surfactant, non-protein blocking reagent provides very low non-specific binding of proteins from the sample matrix
  • 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 1μm diameter provides excellent lot-to-lot reproducibility
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. The surface is then blocked with a non-surfactant, non-protein based method, to help prevent non-specific binding of proteins
