Date Nov. 23, 1995A species such as a microorganism, e.g. Legionella, Giardia or Cryptosporidium, is captured by first attracting plastic coated magneticbeads or other magnetically attractable particles to a solid support such as stainless steel mesh, which particles have a selective affinity for the species, e.g. by virtue of an antibody coating, and contacting a sample containing the species with the particles on the solid support. The beads bearing the captured species may be released by reduction of the magnetic attraction of the support for the beads, e.g. by turning off an electromagnet used to magnetize the support.</p> |
