Magnetic Particles

 
Coated Polystyrene Magnetic Particles
These magnetic particles are prepared by coating a layer of iron oxid and polystyrene onto the core of the particles. They are relativly uniform in size, spherical in shape and paramagnetic in nature. The paramagnetic nature of the particles allows them to be separated by using a magnet but the particles will resuspend easily when removed from the magnet. They will not retain any significant magnetism even after repeat exposure to strong magnetic field.

These magnetic particles can be used for cell separation, affinity purification, DNA probe assays, magnetic particle EIA etc. The coated magnetic particles are prepared by covalent coupling, concentration is around 2 x 108 particles/ml, 0,02% sodium azide added..

The Particles are supplied monodisperse in the described range, the actual size is depending on current lot.nr.

Magnetic Polystyrene Particles
In many experiments the careful separation of cells or cellfragmentes is a problem. Magnetizable ( paramagnetic ) particles have the characteristic, to be magnetizated within a magnetic field. So they can be separeted easy within a solution. Outside of the magnet field the particles are not magnetic. These particles are made by coating a layer of iron oxide and polystyrene onto polystyrene core particles. The particles are useful for cellseparation, coupling of proteines, antibodies and DNA, affinity purification and DNA probe assays. The particles are monodisperse with low SD and a CV of less than 5%. They are supplied as aqueous suspension.
