immunoelectrophoresis
Noun: A laboratory technique that combines the principles of electrophoresis (the movement of charged particles in an electric field) with immunodiffusion (the reaction between an antigen and its specific antibody) to separate and identify complex mixtures of proteins, especially antigens and antibodies, in a sample.
This is a technical, uncountable noun used primarily in scientific contexts such as clinical diagnostics, biochemistry, and immunology. It refers to the method itself. * The diagnosis was confirmed by immunoelectrophoresis of the serum sample. * Immunoelectrophoresis is a classic method for analyzing immunoglobulin abnormalities.
- The research paper detailed the use of immunoelectrophoresis to characterize the monoclonal antibody.
- In the lab, we learned how to perform immunoelectrophoresis to detect specific antigens.
The term is often used in the names of more specific, modern variants of the technique. * Countercurrent immunoelectrophoresis: A faster, more sensitive version where antigen and antibody migrate toward each other in an electric field. * Rocket immunoelectrophoresis (or electrolmmunoassay): A quantitative technique where antigen migrates into a gel containing antibody, forming "rocket"-shaped precipitin peaks.
- Immunoelectrophoretic (adjective): Relating to or obtained by immunoelectrophoresis.
- The immunoelectrophoretic pattern showed a distinct arc.
- Electrophoresis (noun): The foundational technique for separating molecules based on their size and charge.
- Immunodiffusion (noun): A technique for detecting antigen-antibody reactions by their diffusion in a gel.
- Immunoassay (a broader term for any technique measuring an immune response, which includes immunoelectrophoresis).
- Protein electrophoresis (a related but less specific technique that does not involve antibody reactions).
The word immunoelectrophoresis has a single, specific technical meaning in biomedical science. It does not have common idiomatic or phrasal verb uses.
