Radioimmunoassay (RIA) is a competitive assay technique in which the reagent, the antibody (Ab), is used in a limited amount as compared with the amount of analyte antigen (Ag). To perform a RIA, it is essential to have a radioactively labeled antigen (Ag∗), which also is referred to as the tracer. cupy copy to host https://prominentsportssouth.com
