Fresenius' Journal of Analytical Chemistry, 2000
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.

Journal of Immunological Methods, 1997
Various aspects of the application of liposomes as a label in immunoassays are reviewed. Methods for the preparation of liposomes, from the basic film method to the more advanced dehydration-rehydration method, are discussed. Furthermore, the markers used in liposome labels, as well as the methods to conjugate liposomes to antigens or antibodies, are ...

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1987
Immunoassays are routinely used to detect, specifically, low levels of many antigens. The trend away from the use of radioisotopic labels has resulted in a proliferation of alternative labels, many of which have electrochemical activity. The more successful of these assays have used enzyme labels, coupled with amperometric or potentiometric methods of ...

2019Immunoassays (IAs) are analytical methods based on the specific recognition between the antigen (Ag), which molecular weight can vary in a wide range, and the variable regions of antibody (Ab), a Y shaped macromolecule composed by four polypeptide chains.

Human Pathology, 1984
Fluorescence immunoassay is a sensitive technique that can be used in the measurement of many compounds, including drugs, hormones, and proteins; in the identification of antibodies; and in the quantification of antigens such as viral particles and, potentially, bacteria. Homogeneous fluorescence immunoassay, fluorescent excitation transfer immunoassay,

No other development has had such a major impact on the measurement of hormones as immunoassay. Reagents and assay kits can now be bought commercially but not for the more esoteric or new hormones. This chapter explains the basics of the immunoassay reaction and gives simple methods for immunoassays and immunometric assays and for the production of ...
