Additional Magnetic & Iron Oxide Particles
Amino Superparamagnetic Microparticles A2dm
Iron-containing microparticles have a polystyrene surface which allows for passive adsorption
and covalent attachment. Will respond to a magnetic field and easily resuspend when the field is
removed. Useful in a variety of applications that require fast, gentle separation during washing and
isolation procedures. Packaged as 2.5% solids (w/v) aqueous suspensions. Technical Data Sheet #438
