  • Magnetic particles for the separation and purification

    Usually, it is sufficient to apply a magnet to the side of the vessel containing the sample mixture for aggregating the particles near the wall of the vessel and pouring away the remainder of the sample see fig. 1. magnetic carriers with immobilised affinity ligands or prepared from a biopolymer exhibiting affinity to the target nucleic acid are used for the isolation process.

  • Chapter 3 magnetic particle inspection method

    8magnetic flux lines, or lines of force in leakage fields, flow from the north to the south pole. in an ideal horseshoe magnet, the flux lines leave only at the poles and consequently an external magnetic force capable of attracting magnetic materials exists only at the poles. this action provides an example of a longitudinal magnetic field.
