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. WebThe tests are based on the inhibition of I125-Clq or I125-monoclonal rheumatoid factor (mRF) binding to an insoluble substrate, IgG-Sepharose. The assays can be performed in 5 h utilizing 10 micronl of serum. Heating of serum is not required and polyclonal rheumatoid factors do not interefere.
