Overview
Bioluminescence Resonance Energy Transfer (BRET) is a powerful technique used in biomedical research. It involves transferring energy from a donor molecule to an acceptor molecule through the process of fluorescence resonance energy transfer (FRET). The donor molecule is usually bioluminescent, meaning it emits light, while the acceptor molecule is typically fluorescent and absorbs light. This transfer of energy between the two molecules is used for a variety of molecular processes, such as measuring protein-protein interactions, determining enzyme-substrate interactions, and measuring gene expression levels. BRET offers a unique way for researchers to study these interactions and better understand cellular mechanisms, making it an invaluable tool in biomedical research.
