Sera-Mag^™ SpeedBeads Blocked Streptavidin particles

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 provide magnetic bead solutions in scientific research and development. Typical application uses include sample preparation, proteomics, nucleic acid isolation, and immunoassay applications.

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 are available.
• Fast Magnetic Response Times and Stable Physical Integrity
• The cauliflower-like surface structure offers more surface area for binding reactions compared to smooth-surfaced particles
• The particles with uniform, nominal 1 μm diameter provide more consistent and reliable results
• The particles have a non-surfactant and surfactant protein-blocked surface to decrease the adsorption of undesired proteins from the matrix.
• Rapid reaction kinetics improves the throughput, precision, and quick movement through viscous solutions
• Available in Sera-Mag SpeedBeads and original Sera-Mag versions.
• Excellent sensitivity and low nonspecific binding for greater accuracy.
