Yalow, Rosalyn (1921– ) US biochemist. In the 1950s, she found that some people who received insulin injections developed antibodies against the hormone. Yalow discovered that insulin, labelled with radioactive iodine, combined with the antibodies; from this she developed radio-immunological tests to detect and measure the amount of insulin present. Yalow shared the 1977 Nobel Prize in physiology or medicine for her development of a method of detecting peptide hormones in the blood. See also antibody
