Absolute Mag™ Streptavidin Magnetic Particles, PVA, 0.5-1 µm(WHM-C295)

Datasheet Magnetic Beads Bioconjugation

Streptavidin is immobilized covalently on the surface of superparamagnetic polyvinyl alcohol particles. Their high magnetite content permits the rapid separation of biotinylated target molecules. Because of the hydrophilic nature of the polyvinyl alcohol matrix, unspecific binding properties are reduced to a minimum. These beads have a polydisperse size distribution.
