The enzyme immunoassay (EIA) is one of the most powerful of all immunochemical techniques. First described in the early 1970s, these assays are now used routinely in laboratory analyses and diagnostics. In biology and biotechnology, the EIA is a valuable and versatile tool used to detect and quantitate antigens and antibodies.

Clinical Biochemistry, 1989
An immunoassay method based on the labelling of an antigen with a transition-metal carbonyl organometallic marker and detection of the label by Fourier transform infrared (FT-IR) spectroscopy is described. The viability of this novel non-isotopic approach, termed infrared immunoassay (IRIA), has been evaluated in the quantitative determination of the ...

Methods, 2000
Expression immunoassay is a sensitive analytical method that takes advantage of coupled in vitro transcription and translation as a signal amplification technique. Essentially, the immunoassay is performed using a detection antibody that is labeled with an expressible fragment of DNA.

Immunoassays are widely used for medical diagnostics and constitute the principal method of detecting pathogenic agents and thus of diagnosing many diseases. These assays, which are most often performed in well plates, would be greatly improved by a practical method to pattern a series of antigens on a flat surface and to localize their binding to many

Assays employed in the biological sciences fall into two categories, which may be respectively termed "comparative" (or "functionally-specific") and "analytical" (or "structurally-specific"). The former are intended to compare the relative effects of substances, or mixtures of substances--not necessarily of identical chemical structure--on a biological

Immunoassays (IA) use the specific antigen antibody complexation for analytical purposes. Radioimmunoassays (RIA), fluorescence immunoassays (FIA) and enzyme immunoassays (EIA) are well established in clinical diagnostics. For the development of hand-held devices which can be used for point of care measurements, electrochemical immunoassays are ...

Journal of Pharmaceutical and Biomedical Analysis, 1987
The theory of the scattering of light by particles is summarised and the principles underlying instrumentation for nephelometry in immunoassays are outlined. Consideration is given to the various factors that influence nephelometric assays and methods for increasing sensitivity are discussed.
