David Lambert and a panel of leading authorities present a wide range of experimental protocols for studying Ca2+ signaling. These optimized techniques cover the more common applications, including 45Ca2+ flux measurements, and basic fluorometric technology, as well as more sophisticated methods, including confocal microscopy and subcellular Ca2+ imaging. There are also methods - largely based on fluorescence measurement - to determine Ca2+ channel activity and the release of Ca2+ from intracellular stores. Calcium Signaling Protocols offers today's researchers readily reproducible laboratory methods that make it possible to examine the calcium signaling process in detail in a range of cells of animal and plant origin.
