The radiolabelled antigen is then mixed with a known amount of its antibody, resulting in formation of a labelled antigen-antibody complex, called bound antigen. Radioimmunoassay RIA. Insulin is, relatively speaking, a small molecule, and the medical wisdom of the day said that only massive molecules could trigger antibody responses. She shared the prize money with two other scientists, Andrew Schally and Roger Guilleman as Solomon Berson was no longer alive when the announcement was made.

In using radioactive-labelled material this analytical technique combined the technology of nuclear medicine tracer technique and immunology antigen-antibody binding.

Injecting radiosotopically labeled substances into the blood and taking samples after the injected material had been mixed uniformly, they developed a method of discerning the quantity of blood cleared of iodine by the thyroid gland per unit of time, providing a quick determination of thyroid activity.

The unexpected finding that radiolabeled insulin disappeared more slowly in patients who had received prior insulin injections led Yalow and her colleague Solomon Berson to postulate that the presence of the foreign insulin triggered antibody production.
