WebJul 6, 2016 · Immunoassays are quick and accurate tests that can be used on-site and in the laboratory to detect specific molecules. Immunoassays rely on the inherent ability of an antibody to bind to the specific structure of a molecule. Antibodies are proteins generated by animals in response to the invasion of a foreign molecule (antigen) into the body. WebAug 26, 2024 · Immunoassay is widely used in food production and development to detect dangerous contaminants or allergens.
