This volume discusses the latest techniques used by researchers to measure cAMP activity at the cell population, whole cell, and subcellular level. The techniques covered in the book address questions related to cAMP compartmentalization, which look at relevant protein-protein interactions that increase the spatial and temporal resolution of cAMP signals detection, and that can help in the integration of the increasingly complex information that is becoming available in this field. Written in the highly successful series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory prools, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, is a valuable resource for scientists and researchers who are interested in learning more about this important and developing field.
