Absolute Mag™ PEI Magnetic Polystyrene Particles, 6 µm(WHM-G150)

Datasheet

Absolute Mag™ PEI Magnetic Polystyrene Particles, 6 µm (# WHM-G150) are monodisperse magnetic particles, consisting of magnetite around an organic matrix of a polystyrene polymer, and finally coated with a polymer layer for the encapsulation of magnetite. These particles are designed with a polyethylenimine (PEI) coating for binding and magnetic separation of nucleic acids. These magnetic particles can easily be separated with a conventional permanent magnet. Standard deviation: < 5 % (C.V.).
