Fluorescent Probes Used for Measuring Intracellular Calcium


Calcium signals are produced by sudden increases in the intracellular calcium concentration. The most effective techniques for measuring this concentration use fluorescent or luminescent probes. Two types of probe are widely used: those that undergo a change in fluorescence when calcium is bound, and those that emit light when calcium is bound.

Keywords: calcium ions; fluorescent probes; calcium signals; calcium in organelles; localization of probes
