A researcher is comparing surface antigens X and Y from two distinct viruses. He acquires antigen X antibodies from an animal that has previously been exposed to the virus encoding this antigen. After that, the antibodies are added to test plates. Following that, a set amount of radiolabeled X antigen is applied to the plates. Unlabeled Y antigens are then given to each plate in escalating quantities, and the plates are washed to eliminate unbound antigens. The graph below depicts radioactivity as a function of Y antigen concentration. . Which of the following best describes the results of this experiment?

Eductional Objective: A radioimmunoassay determines the amount of antigen contained in an unknown sample by using particular antibodies and a set amount of radiolabeled antigen. This is accomplished by measuring the quantity of radiolabeled antigen displaced from the system's antibodies.
