The cell-impermeant Fura-8FF is an analog of Fura-8 with much lower calcium binding affinity, Kd ~10 µM. Fura-8FF has its emission shifted into longer visible wavelength that is compatible with the common filter sets. e., calculating the excitation intensity ratios at 354 nm and 415 nm by monitoring emission intensity at 530 nm.
