The enzyme-linked immunosorbent assay ( ELISA) is a commonly used analytical biochemistry assay. It uses ligand binding via antibodies and antigens to quantify a substance by the reaction's colour change. The ELISA has been used as a diagnostic tool in medicine and plant pathology, and as a quality control check in various industries.
