Nonsurfactant, nonprotein blocking reagent provides very low nonspecific 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 cauliflowerlike surface provides increased area for binding reactions compared to smooth surface particles Uniform, nominal 1 μm diameter provides excellent lot-to-lot reproducibility. SeraMag™ SpeedBeads™ StreptavidinBlocked Magnetic Particles combine fast reaction kinetics with very low nonspecific 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. SeraMag™ SpeedBeads™ and SeraMag™ StreptavidinCoated Magnetic Particles provide a high biotinbinding capacity along with a strong affinity for targeted, biotin labeled molecules. SeraMag 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 nonsurfactant, nonprotein based method, to help prevent nonspecific binding of proteins.
