Absolute Mag™ PEG-COOH Magnetic Polystyrene Particles, 3 µm(WHM-G139)

Datasheet

Absolute Mag™ PEG-COOH Magnetic Polystyrene Particles, 3 µm (# WHM-G139) 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 PEG-COOH groups on the surface for the covalent binding of proteins, antibodies or other molecules by carbodiimide chemistry. These magnetic particles can easily be separated with a conventional permanent magnet. Standard deviation: < 5 % (C.V.).
