Abstract
Antigens and their antibodies are measured in a combined radioimmunoassay by incubating a sample of an unknown fluid with a known quantity of an antibody, contacting the mixture obtained with the walls of a vessel having a coating of known antigen content, again incubating, then aspirating the mixture and washing the walls of the vessel, adding a pure radioactive tracer antigen, aspirating and washing again, and finally measuring the radioactivty of the coated parts conventionally, e.g., in a gamma counter known in the art.
