Protocol
-
Calcium Spark Assay
Calcium sparks are localized, transient increases in intracellular calcium concentration ([Ca2+]i) that occur in cardiac myocytes and represent elementary events underlying excitation-contraction coupling. These events are generated by the coordinated opening of clusters of ryanodine receptors (RyRs) on the sarcoplasmic reticulum membrane, leading to a brief release of Ca2+ into the cytosol. The detection and analysis of calcium sparks provide insights into the mechanisms of calcium handling and signaling in cardiac cells. Imaging techniques using fluorescent calcium indicators such as Fluo-3 are employed to visualize these subcellular calcium transients with high spatial and temporal resolution. The protocol is based on established methodologies described in primary literature for both experimental measurement and automated analysis of calcium sparks.
