Opis ogólny

Fura 2-AM (Fura 2), also known as acetoxy-methyl-ester, is a calcium-specific ratio-metric fluorescent dye. 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.

Zastosowanie

Fura 2-AM is a popular probe used to determine dynamic changes in cytosolic free calcium in intact living cells.

Cechy i korzyści

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.
Other advantages 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.

Inne uwagi

Membrane-permeable derivative of Fura-2. Used to load the chelator into cells. Hydrolysed enzymatically in the cell to yield Fura-2 which remains within the cell
