Sera-Mag and SpeedBead technology

The core of each 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. Due to the extra magnetite layer, SpeedBeads respond twice as fast to a magnetic field as the original Sera-Mag particles.

Customized for your workflows Magnetic particles may need further processing before they are ready to use for your particular application. Therefore, we can provide personalized magnetic bead solutions that fit seamlessly into your workflows, often saving you time and money in the process. We aim to provide product that is ready to use with little or no need for further modification. This allows you to focus on the science that matters.

The core of the particle is made from free radical emulsion polymerization of styrene and acid monomers. This, combined with the two layers of magnetite that coat the core, cause Sera-Mag SpeedBeads to respond twice as fast. The surface of the particle is then blocked with a non-surfactant, non-protein based method, helping to prevent non-specific binding of proteins.

Typical molecular biology applications include: nucleic acid isolation, next generation sequencing (NGS) and clinical diagnostic immunoassays.

Have you considered your magnetic separation rack?

Cytiva’s Magnetic Separation Rack 15 mL is a 3D printed, magnetized tube rack with a strong, removable magnetic force and easy pipette access. It facilitates high capture, retention, and release of magnetic beads from various liquid sample media, allowing high-throughput, parallel processing of up to six 15 mL samples.
