This volume details methods on several aspects of circadian research. Chapters guide readers through the latest techniques and a wide variety of daily rhythmic processes, model organisms, circadian rhythms in the SCN and in peripheral organs, and describing in vitro systems and in silico methods. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols. Authoritative and cutting-edge, Circadian Regulation: Methods and Protocols aims to be a useful practical guide to researches to help further their study in this field.
