Focused on the handling of living components, this highly versatile station serves in particular to quantify the exchanges between cellular compartments or to measure the protein diffusion rate according to different experimental conditions (“FRAP” techniques). For its part, optogenetics (or photoactivation) is a recent technique, originally used in neurology and whose areas of application are progressively expanding. It is used at the TRI platform in particular for activating and inactivating DNA transcription or protein production. Finally, photoablation makes it possible to use light as a knife to observe the fate or remodeling of DNA molecules, cell membranes and cytoskeletons.
