In circadian research, it is essential to be able to track a biological rhythm for several days with the minimum perturbation for the organisms or tissues. The use of transgenic mice lines, in which the luciferase reporter is coupled to a molecular clock protein (here PERIOD2), gives us the opportunity to follow the circadian activity in different tissues or even single clock cells for days without manipulation. This method creates sections using a mouse brain matrix, which allows us to obtain several brain samples quickly at a single time point.
