 Magnetic immunoassay

Magnetic immunoassay (MIA) is a novel type of diagnostic immunoassay using magnetic beads as labels in lieu of conventional enzymes (ELISA), radioisotopes (RIA) or fluorescent moieties (fluorescent immunoassays) to detect a specified analyte.MIA involves the specific binding of an antibody to its antigen, where a magnetic label is conjugated to one element of the pair.
