  1. radioimmunoassay

    Radioimmunoassay is a scientific method used in research and clinical laboratories to measure the concentration of specific antigens (substances that initiate an immune response) in a solution using the principles of antibody-antigen binding and radioactive labeling. It's often used to detect hormones, drugs, tumour markers and many other substances in the body.

  1. Radioimmunoassay

    Radioimmunoassay is a very sensitive in vitro assay technique used to measure concentrations of antigens by use of antibodies. As such, it can be seen as the inverse of a radiobinding assay, which quantifies an antibody by use of corresponding antigens. Although the RIA technique is extremely sensitive and extremely specific, requiring specialized equipment, it remains the least expensive method to perform such tests. It requires special precautions and licensing, since radioactive substances are used. Today it has been supplanted by the ELISA method, where the antigen-antibody reaction is measured using colorimetric signals instead of a radioactive signal. However, because of its robustness, consistent results and low price per test, RIA methods are again becoming popular. It is generally simpler to perform than a bioassay. The RAST test is an example of radioimmunoassay. It is used to detect the causative allergen for an allergy.

  1. Radioimmunoassay

    Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
