Half of the prize will go to Rosalyn Yalow, 56, a nuclear physicist by training who decided early in her career to do medical research. In the 1950s, while working on the complex chemistry of diabetes at the Veterans Administration Hospital in The Bronx, N.Y., Yalow and her late collaborator, Dr. Solomon Berson, devised a sensitive new biological analytic technique called the radioimmunoassay (RIA). Using radioactive isotopes as tracers in the so-called immune reactions by which the body's antibodies combine with foreign antigens, the test was sensitive enough to detect exceedingly minute quantities of a substance...
...Cited for basic research was Rosalyn S. Yalow of the Bronx Veterans Administration Hospital, both the first woman and first nuclear physicist to win a Lasker prize. Together with the late Dr. Solomon A. Berson, she developed a sophisticated new tool called radioimmunoassay (RIA) for measuring minuscule quantities of pharmacological and biological substances. Using radioactive isotopes as tracers in antigen-antibody reactions, the technique is becoming increasingly important in everything from diagnosing disease to finding poisons in murder victims...
