Sera-Mag™ SpeedBeads Streptavidin-Blocked Magnetic Particles

Sera-Mag SpeedBeads Streptavidin-Blocked Magnetic Particles combine high affinity for biotinylated target molecules with very low nonspecific binding.

- Very high binding capacity and low non-specific binding for biotinylated target molecules on-surfactant due to non-protein blocking reagent
- Fast reaction kinetics increases throughput and precision, enabling faster movement through viscous solutions
- Unique cauliflower-like surface structure provides increased surface area for binding reactions compared to smooth-surfaced particles
- Uniform, nominal 1 μm and 3 μm diameters provide excellent lot-to-lot reproducibility
- Also available as custom manufactured beads
Sera-Mag™ SpeedBeads streptavidin-blocked magnetic particles now available in 1 µm and 3 µm nominal diameters.

Sera-Mag Streptavidin Magnetic SpeedBeads can be used for applications such as DNA purification, Next Generation Sequencing (NGS) library prep, 5’ Rapid Amplification of cDNA Ends (RACE), cDNA library prep, sequence enrichment of low abundance cDNA, automated immunoassays, immunoprecipitation, and protein purification.

Streptavidin coating targets biotinylated molecules
Compounds that are difficult to attach to particle surfaces by conventional means may be amenable to biotinylation. Sera-Mag SpeedBeads and Sera-Mag Streptavidin-Coated Magnetic Particles provide a high biotin-binding capacity along with a strong affinity for targeted, biotin-labeled molecules.

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.

Customized magnetic bead solutions that fit seamlessly into your workflows can be developed for a particular application, often saving you time and money. The product can be provided ready-to-use with little or no need for further modification allowing you to focus on your research. To learn more, please visit our custom manufacturing services page.
