Radioimmunoassay vs immunoassay
WebAn ELISA, like other types of immunoassays, relies on antibodies to detect a target antigen using highly specific antibody-antigen interactions. Basic ELISA principles (H2) In an ELISA assay, the antigen is immobilized to a solid surface. This is done either directly or via the use of a capture antibody itself immobilized on the surface.

Immunoassays employ a variety of different labels to allow for detection of antibodies and antigens. Labels are typically chemically linked or conjugated to the desired antibody or antigen. Possibly one of the most popular labels to use in immunoassays is enzymes. Immunoassays which employ enzymes are referred to as enzyme immunoass…
WebA dose-response curve can then be used to extrapolate the concentration of sample antigen. Two commonly used methods of RIAs are double-antibody RIA and coated-tube RIA. Radioimmunoassays are sensitive and can be used for drug detection. Visit the radioimmunoassay kit suppliers for more details, including specificity and kit components. WebImmunoassays have virtually replaced bioassays for detection of pregnancy. Slide and tube tests are applicable in most clinical situations. Because of its sensitivity, radioimmunoassay is ideal for diagnosis of early and ectopic pregnancies. PIP: Sensitivity and accuracy of pregnancy tests are reviewed.
