radioimmunoelectrophoresis

Definition

A laboratory technique combining radioisotope labeling with immunological methods and electrophoresis to separate and identify specific proteins or antigens in a sample. This specialized analytical method uses radioactive markers attached to antibodies to detect and measure protein concentrations with high precision.

Example Usage

The researchers used radioimmunoelectrophoresis to identify hormone levels in the patient's blood serum.

Origin

Compound of radio- (from Latin radius, ray), immuno- (from immunity), and electrophoresis (from Greek elektron, amber, and phoresis, carrying).

Fun Fact

This technique was particularly important in endocrinology research during the 1960s-1980s before modern mass spectrometry became widespread.
