In this volume of Methods in Molecular Biology™, expert investigators offer comprehensive, complementary, and cutting-edge technologies for studies of gene regulation. The chapters of Gene Regulation: Methods and Protocols are organized to provide an integrated and a coherent view of control systems and their associated components. The protocols are broad in their scope. They include molecular, biochemical, spectroscopic techniques as well as high throughput strategies. 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 key tips on troubleshooting and avoiding known pitfalls. Comprehensive and broad in their scope, the protocols are useful to researchers in many disciplines including molecular biology, genomics, biochemistry, biomedicine, nutrition, and agricultural sciences.
