Fura 2-AM ≥95% (par HPLC)
Fura 2-AM
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 505 nm, and the excitation peak ranges between 340 to 380 nm and is the preferred calcium indicator.
- Fura 2-AM is a popular probe used to determine dynamic changes in cytosolic free calcium in intact living cells
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.
