ELISA (enzyme-linked immunosorbent assay) is a commonly used plate-based assay technique first described in the 1970's. ELISAs are used to measure antibodies, antigens, and proteins that are found in biological samples, such as serum, cell lysates, and other fluids. While in-house development of ELISA assays is possible, most researchers buy validated ELISA kits to simplify their workflow. A common ELISA kit format is the sandwich ELISA, where the assay uses a capture antibody to bind the target antigen found in a sample and a detection antibody that is labeled with an enzyme that converts the assay substrate, such as TMB, into a colored product that can be measured using a plate reader.
