Absolute Mag™ Streptavidin Magnetic Nanoparticles, Dextran Coated, 500 nm (# WHM-G047) are synthesized as a core of magnetite and coated with dextran shell. These nanoparticles are designed with covalently bound streptavidin on the surface for binding of biotinylated molecules with a high affinity. These magnetic nanoparticles are cluster-typed shaped and can be separated with a permanent magnet. Polydispersity index: < 0.2.
