Abstract
A method for collecting a specimen comprising (1) subjecting a specimen and a magnetic-labeled antibody comprising a magnetic micro-particle and an antibody fixed to the micro-particle to an immunoreaction to form a reacted immunocomplex, (2) concentrating the reacted immunocomplex locally at a selected region by applying an external magnetic field, preferably a gradient magnetic field, which is produced by an electromagnet and a permanent magnetic piece so as to concentrate the magnetic flux at the selected region, and (3) collecting the immunocomplex by direct magnetic adsorption toward the magnetic pole at the region of local concentration.
