Collection of Mouse Brain Slices for Bioluminescence Imaging of Circadian Clock Networks

Methods Mol Biol. 2021:2130:287-294. doi: 10.1007/978-1-0716-0381-9_21.

Abstract

Circadian rhythms in cellular function can be monitored in real time with bioluminescence imaging. In this approach, bioluminescence is produced by an enzymatic reaction, which can be used to report dynamic changes in gene or protein expression in living cells. Bioluminescence imaging in circadian experiments typically uses an ex vivo slice preparation, with the most commonly studied structure being the master clock in the suprachiasmatic nucleus (SCN) of the anterior hypothalamus. Here we describe procedures for dissecting and collecting SCN slices for bioluminescence imaging experiments.
