![]() After washing, all unbound antibodies are removed from the plate, and an enzyme substrate is applied after washing. ![]() An identical antibody tied to an enzyme is applied for the antigen to bind to it. There are four different types of ELISA methodsĪn antigen from the sample is attached to a polystyrene plate during the ELISA method. Elisas are also instrumental for cytokine analysis for widespread applications, including those for neurological diseases. A gold standard of immunoassays, ELISAs are highly sensitive and a simple method of measuring the presence of proteins in various samples such as urine, serum or cell culture. The indirect sandwich enzyme-linked immunosorbent assay, or ELISA, is a cost-effective analytical tool commonly used to analyse antibodies, antigens, proteins, and glycoproteins. We also provide HHV-6 IgG antibody and KSHV/HHV8 IgG antibody ELISA kits.
