  • Fast reaction kinetics and low nonspecific binding increase throughput and precision in a variety of immunoassay and molecular biology applications.
  • Even coating of Neutravidin™ protein provides reliable results.
  • Low non-specific binding for fast and clean purification.
  • 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 Neutravidin™-Coated Magnetic Particles combine fast reaction kinetics and low non-specific binding for increased throughput and precision in immunoassay and molecular biology applications, including sample preparation and assay development for genomics and proteomics applications.
  • Sera-Mag SpeedBeads Neutravidin™-Coated Magnetic Particles exhibit high affinity when binding to biotinylated ligands such as proteins, nucleic acids, and peptides. The particles are available with a 3500-4500 pmol/mg biotin-binding range.
  • 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, while the surface is modified to minimize non-specific binding of proteins. Neutravidin™ (NA) is then covalenty bound to the particle surface.
  • 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.
