Enzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits.
