Molecular formula:C50H50N2O23,
Nature:Synthetic,
Solubility:Soluble in DMSO,
Biological description:Medium affinity green fluorescent calcium binding dye. Binds to intracellular calcium (Kd = 390 nM). Fluorescence intensity increases upon Ca2+ binding. Cell-permeable.Fluo-8 (or Fluo-2 Medium Affinity) has been found to be brighter (1.5x) than Fluo-4 in cellular experiments. It offers improved cell loading and Ca2+ response while maintaining the convenient Fluo-3 and Fluo-4 spectral wavelength of maximum excitation at 490 nm and maximum emission at 520 nm. Fluo-8 loading can be performed at room temperature.,

Product details:
Fluo-8® AM Working Solution: On the day of the experiment, either dissolve Fluo-8® AM in DMSO or thaw an aliquot of the indicator stock solution to room temperature. Prepare a dye working solution of 2 to 20 µM in a buffer of your choice (e.g., Hanks and Hepes buffer) with 0.04% Pluronic® F-127. For most cell lines, Fluo-8® AM at a final concentration of 4-5 μM is recommended. The exact concentration of indicators required for cell loading must be determined empirically.
