General description

Sera-Mag SpeedBeads and Sera-Mag Carboxylate-Modified Magnetic 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. Covalent coupling of biomolecules such as proteins and nucleic acids to carboxyl groups on the surface is easily accomplished using our standard coupling technology. The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. One (Sera-Mag) or two (Sera-Mag SpeedBeads) layers of magnetite are then coated onto this core, while the surface is modified to minimize non-specific binding of proteins.


Sera-Mag SpeedBeads and Sera-Mag Carboxylate-Modified Magnetic Particles typical application uses include sample preparation, proteomics, nucleic acid isolation, and immunoassay applications.

Features and Benefits

Sera-Mag SpeedBeads and Sera-Mag Carboxylate-Modified Magnetic Particles allow convenient covalent coupling of target molecules.

  • Carboxylic groups on the surface permit easy covalent coupling to biomolecules of interest using convenient carbodiimide chemistry.
  • Different levels of hydrophobicity/hydrophilicity available.
  • Available in Sera-Mag SpeedBeads and original Sera-Mag versions.
  • Excellent sensitivity and low nonspecific binding for greater accuracy.
  • Fast Magnetic Response Times and Stable Physical Integrity
