Cytiva's Whatman™ 21152104010150 Sera-Mag™ SpeedBead Streptavidin-Blocked Magnetic Particle, Pack Size: 5mL, Storage Condition: 4°C

Sera-Mag SpeedBeads Streptavidin-Blocked Magnetic Particles combine high affinity for biotinylated target molecules with very low nonspecific binding. Non-surfactant, non-protein blocking reagent provides very low non-specific binding and high binding capacity for biotinylated target molecules. 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 1 μm diameter provides excellent lot-to-lot reproducibility. Sera-Mag SpeedBeads Streptavidin-Blocked Magnetic Particles combine fast reaction kinetics with very low non-specific binding for increased throughput and precision. Applications include 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. As magnetic particles may need further processing before they are ready to use for your particular application, 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 allowing you to focus on the science that matters.
