Visualizing Protein-Protein Interactions by Non-Fitting and Easy FRET-FLIM Approaches

In this Webinar, Dr. Padilla-Parra shows how much information you can harness from FRET. He explains how lifetime-based non-fitting approaches such as minimal fraction of interacting donors (mFD) can provide a direct readout of protein-protein interactions in the cellular environment over time. He also talks about some of the limitations of classical FRET approaches.

After the presentation, Dr. Zhongxiang Jiang gives a live showcase at the STELLARIS 5 confocal system with an integrated White Light Laser (WLL), combined with the proprietary Acousto-optical Beam Splitter (AOBS) and new Power HyD S detectors. He shows the straightforward application of lifetime-based non-fitting FRET using the new and unique TauSense technology.
