Fig. 3. A magnetic immune-separation process and LFA. In step 1, antibody-immobilized magnetic beads were injected into a tube. Using the magnetic field generated by an external magnet, the target antigens were gathered and unbound antigens were removed by a pipette, in step 2. By applying the magnetic beads to the LFA strip, the presence of the target antigens was detected.
