This volume presents techniques used by researchers from all branches of biology to study daily changes at a molecular level in many physiological systems. The chapters are organized into three parts and cover topics such as measuring and modeling physiological and behavioral rhythms; genome-wide analyses in circadian biology, and imaging and manipulating brain clocks. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and practical, Circadian Clocks: Methods and Protocols is a valuable tool for any researcher interested in learning more about this developing field.
