Single-Cell Ca2+ Imaging.

Abstract

In rheumatological studies, visualization of Ca2+ dynamics in intact cells as direct experimental evidence of Ca2+-dependent signal pathways is generally used to monitor the function of immune cells at first glance. Ability to monitor Ca2+ signaling in living cells would greatly facilitate advances in the functional dissection of immune cells. In this chapter, we describe a basic technique and methods of data analysis for single-cell real-time Ca2+ monitoring using Fluo-4 labeling, which is a single-wavelength Ca2+ indicator.
