ELISA (also known as enzyme immunoassay, EIA) offers the same sensitivity as radioimmunoassay without the inherent disadvantages of expensive isotopes of short half-life and the need for safe handling and disposal and a costly gamma counter.The basic principles are similar to those of radioimmunoassay (Fig. 13-3).Antibody is bound to a solid phase, usually the wells of a microtiter tray The enzyme-linked immunosorbent assay (ELISA) (/ ɪ ˈ l aɪ z ə /, / ˌ iː ˈ l aɪ z ə /) is a commonly used analytical biochemistry assay, first described by Engvall and Perlmann in 1971. The assay uses a solid-phase type of enzyme immunoassay (EIA) to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the protein to be measured en·zyme im·mu·no·as·say any of several immunoassay methods that use an enzyme covalently linked to an antigen or antibody as a label; the most common types are enzyme-linked immunosorbent assay (ELISA) and enzyme-multiplied immunoassay technique (EMIT).

Enzyme multiplied immunoassay: In the Enzyme multiplied Immunoassay (EMIT), the drug in the sample and the drug labeled with G6PD compete for antibody binding sites. Binding inhibits enzyme activity, while free enzyme remains active to interact with. Enzyme activity/absorbance is directly proportional to drug concentration. iii

[1 An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes). The molecule detected by the immunoassay is often referred to as an analyte and is in many cases a protein, although it may be other kinds of molecules, of different size and types, as long as. Other assays, such as Enzyme multiplied immunoassay technique (EMIT) 17 and Fluorescence polarization immunoassays (FPIA) 18 do not require this separation, and are classified as homogenous immunoassays. EMIT requires an enzyme-linked antigen that will compete with sample antigen for antibody binding What is enzyme immunoassay, and how does it work? 5 March 2015 Enzyme immunoassay (EIA) is now widely used as a diagnostic tool in various industries as well as medicine.

Introduction • The first immunoassay applications in the clinical laboratories often involved detection with radioactive compounds. These radioimmunoassays (RIAs) have now been replaced by enzyme immunoassays (EIA), which offer easy and nonhazardous detection of antigens or antibodies in clinical samples Enzyme Immunoassay (Eia) As in fluorescent antibody tests, the antibody in EIAs is conjugated with a marker that can be detected when an antigen-antibody reaction has taken place. In EIAs, the marker is an enzyme, typically alkaline phosphatase or horseradish peroxidase Medical definition of enzyme immunoassay: an immunoassay (as an enzyme-linked immunosorbent assay) in which an enzyme bound to an antigen or antibody functions as a label —abbreviation EIA Review and cite ENZYME IMMUNOASSAY protocol, troubleshooting and other methodology information | Contact experts in ENZYME IMMUNOASSAY to get answer
