radioimmunoelectrophoresis

radioimmunoelectrophoresis

 [ra″de-o-im″u-no-e-lek″tro-fah-re´sis]
electrophoresis in which any layer of precipitate is identified by adding the corresponding radioactive-labeled antigen or antibody and subjecting it to autoradiography.

ra·di·o·im·mu·no·elec·tro·pho·re·sis

(rā'dē-ō-im'yū-nō-ē-lek'trō-fō-rē'sis),
Immunoelectrophoresis in which the antigen or antibody is labeled with a radioisotope; for example, 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.

Immunoelectrophoresis in which the antigen or antibody is labeled with a radioisotope.

radioimmunoelectrophoresis

electrophoresis in which a particular antigen is identified by adding the corresponding radioactive-labeled antibody and subjecting the gel to autoradiography.
