Immunomagnetic separation (IMS) is a laboratory tool that can efficiently isolate cells out of body fluid or cultured cells. It can also be used as a method of quantifying the pathogenicity of food, blood or feces. DNA analysis have supported the combined use of both this technique and Polymerase Chain Reaction (PCR). [1]
The column consists of steel wool which increases the magnetic field gradient to maximize separation efficiency when the column is placed between the permanent magnets. Magnetic-activated cell sorting is a commonly used method in areas like immunology, cancer research, neuroscience, and stem cell research.
Methods of cell sorting fall into two major categories: fluorescence-activated cell sorting (FACS) and immunomagnetic cell sorting. [2] Due to many years of refinement and increased demand for cell separation however, researchers are working to develop microfluidic sorting devices that have many benefits in comparison to the main types of fluorescence-activated cell sorting and immunomagnetic ...
Magnetic separation techniques are also used in microbiology. In this case, binding molecules and antibodies are used in order to isolate specific viable organisms, nucleic acids, or antigens. [9] This technology helps isolating bacterial species to identify and give diagnostics of genes targeting certain organisms. [9]
Pathatrix and its Pathatrix Recirculating Immunomagnetic Separation System (RIMS) was used in 2006 to detect the E. coli O157:H7 strain in contaminated spinach using a polymerase chain reaction (PCR). The Pathatrix system is used by regulatory agencies and food companies around the world as a reliable method for detecting pathogens in food.
poisoned by methylmercury-contaminated bread in Iraq accumulated higher mercury concentrations in their blood than did their mothers (Amin-Zaki et al., 1988)

Magnetic immunoassay (MIA) is a type of diagnostic immunoassay using magnetic beads as labels in lieu of conventional enzymes (), radioisotopes or fluorescent moieties (fluorescent immunoassays) [1] to detect a specified analyte.
