FRET Assay System Diagram - Lab Equipment Setup for Molecular Interaction Studies #143323 (License: Personal Use)

This schematic illustrates a fluorescence resonance energy transfer (FRET) assay system where a donor cell and receptor cell are connected via microfluidic channels to a temperature-controlled bath and peristaltic pump. A refractive index detector monitors changes in optical properties as energy transfers between fluorophores, while a computer records real-time data. The setup enables precise quantification of molecular binding events under controlled thermal conditions.

Used in academic and industrial research labs for studying protein-protein interactions, enzyme kinetics, or ligand-receptor binding; commonly appears in methods sections of papers, lab protocol guides, or educational materials on biophysical techniques.
