Radioimmunoassay and elisa
WebELISA is an immunoassay based on the catalytic properties of biological enzymes and specific recognition of antigens and antibodies [47], ... For example, Foti et al. [84] developed the first PAP-specific radioimmunoassay (RIA) with high sensitivity and specificity. Besides, other types of RIAs have also been developed. WebA radioimmunoassay ( RIA) is an immunoassay that uses radiolabeled molecules in a stepwise formation of immune complexes. A RIA is a very sensitive in vitro assay technique used to measure concentrations of substances, usually measuring antigen concentrations (for example, hormone levels in blood) by use of antibodies .

Web9.6 Enzyme-Linked Immunosorbent Assay (ELISA) in Diagnostics. ELISA is also known as a solid-phase enzyme immunoassay that is used to detect the presence of a specific protein (antigen or antibody) in blood samples. The basic principle of ELISA is to use an enzyme to detect the binding of antigen (Ag) or antibody (Ab). WebELISA uses an enzymatic reaction as the basis of detection, rather than a radioactive signal. While early versions did not rival the sensitivity of the RIA, the development of highly …
