WebOverview. Radioimmunoassays (RIAs) use antibodies to detect and quantitate the amount of antigen (analyte) in a sample. These assays are typically very sensitive and specific. It is possible to detect as low as a few picograms of analyte in the experimental tube when using antibodies of high affinity (Kd = 10 -8 - 10 -11 M). WebEnzyme-linked immunosorbent assay (ELISA) is a test which employs antibodies and color change to identify substances. Early immunoassays were radioimmunoassays (RIAs), where labels on antibodies were radioactive molecules such as iodine-125. In this assay’s final step, the enzyme (when present) converts substrates to detectable molecules. red and cream bedding set
