radioimmunoelectrophoresis

radioimmunoelectrophoresis
Immunoelectrophoresis in which the antigen or antibody is labeled with a radioisotope; e.g., in testing for insulin-binding antibodies by treating the test serum with radioactive iodine-labeled insulin, subjecting the mixture (antigen) to electrophoresis, precipitating the separated immunoglobulins with immunoglobulin-specific antiserum, and, then, with radiosensitive film (autoradiography), testing for bound insulin in the precipitates.
