Affinity electrophoresis is a technique used to separate and analyze biomolecules based on their affinity for specific ligands. This accurate separation can be used in a range of applications such as drug discovery, protein purification, and clinical diagnostics. Synonyms for affinity electrophoresis include immunoaffinity electrophoresis, ligand electrophoresis, and biospecific interaction analysis. Immunoaffinity electrophoresis is highly specific as it utilizes the binding affinity between an antibody and its antigen. Ligand electrophoresis uses the binding affinity between a ligand and its target protein to separate them. And biospecific interaction analysis measures and quantifies the interactions between molecules or cells. These synonyms for affinity electrophoresis help researchers to describe, explain, and understand their experiments using various terms that match their research goals.
