Bioluminescence Resonance Energy Transfer (BRET) Imaging in Living Cells: Image Acquisition and Quantification.
Institute for Research in Immunology and Cancer (IRIC), Université de Montréal, Montréal, QC, Canada.
Bioluminescence resonance energy transfer (BRET) is an energy transfer phenomenon from a luciferase donor to a fluorescence acceptor and serves as an indicator of protein-protein interaction or protein proximity. BRET imaging is a powerful tool in the investigation of signaling proteins because it enables spatial analysis of such protein interactions. Here, we describe a method exerting high-resolution BRET imaging by combining bright-light output luciferases, such as NanoLuc , photon-counting EM-CCD, and unique algorithms for image correction and denoising.
