Abstract

The measurement and manipulation of cytosolic free Ca2+ of neutrophils is crucial for investigating the mechanisms within living neutrophils which generate Ca2+ signals and the cellular responses triggered by them. Optical methods for this are the most applicable for neutrophils and are discussed here, especially the use of fluorescent indicators of Ca2+ and photoactivation of reagents involved in Ca2+ signaling. Both of these synthetic agents can be loaded into neutrophils as lipid-soluble esters or can be microinjected into the cell. In this chapter, we will outline some of the techniques that have been used to monitor, visualize, and manipulate Ca2+ in neutrophils.
