Fura 2-AM (Fura 2) is a calcium-specific ratio-metric fluorescent dye. It is also known as acetoxy-methyl-ester. In response to calcium ions, ratio metric dyes like Fura 2 changes their respective excitation or emission spectra. The intracellular calcium concentration is determined by the fluorescence emission ratio or excitation at distinct wavelengths. Fura 2 has an emission peak at 505nm, and the excitation peak ranges between 340-380nm and is the preferred calcium indicator.
Application
Fura 2-AM is a popular probe used to determine dynamic changes in cytosolic free calcium in intact living cells.
Features and Benefits
The major benefits of using the ester form of Fura 2 as Fura 2-AM are: It is cell-permeable. It can be loaded into cells easily. Another advantage of using Fura 2-AM over single wavelength dyes is that the ratio signal is independent of : The dye concentration. Illumination intensity, and Optical path length.

To establish whether the thromboxane A2 (TXA2) receptor (TP) functionally couples to the Gq family of heterotrimeric G proteins in vivo, we have coexpressed the cDNAs coding for the human platelet/placental TP alpha isoform (TP alpha) and the alpha subunits
Fura-2 has become the most popular fluorescent probe with which to monitor dynamic changes in cytosolic free calcium in intact living cells. In this paper, we describe many of the currently recognized limitations to the use of Fura-2 in living
