Fura-2: A fluorescent calcium chelating agent which is used to study intracellular calcium in many tissues. The fluorescent and chelating properties of Fura-2 aid in the quantitation of endothelial cell injury, in monitoring Atp-dependent calcium uptake by membrane vesicles, and in the determination of the relationship between cytoplasmic free calcium and oxidase activation in rat neutrophils.

Calcium Imaging in Neurons

JoVE 5203

Calcium ions play an integral role in neuron function: They act as intracellular signals that can elicit responses such as altered gene expression and neurotransmitter release from synaptic vesicles. Within the cell, calcium concentration is highly dynamic due to the presence of pumps that selectively transport these ions in response to a variety of signals. Calcium…
