Mag-Fura-2, Tetrapotassium salt

Description: Among the ratiometric calcium indicators, Fura-2 and Indo-1 are most commonly used.

Description: In contrast to single-wavelength indicators such as Fluo-4, the absorption (or fluorescence excitation) maximum of Fura indicators shifts from 380 nm (Fura-2), 415 nm (Fura-8â„¢ and Fura-10â„¢) for the Ca2+-free chelator to about 340 nm (Fura-2), 355 nm (Fura-8â„¢ and Fura-10â„¢) for the Ca2+-bound .

Description: Although Fura-2 has become the preferred excitation-ratioable calcium indicator of choice, it has certain limitations (e.g., lower sensitivity than single wavelength calcium indicators such as Fluo-8® and Cal-520®).

Description: The cell-impermeant Fura-8FF is an analog of Fura-8 with much lower calcium binding affinity, Kd ~10 µM.

Description: Fura Red is a visible light-excitable fura-2 analog that offers unique possibilities for ratiometric measurement of calcium ion in single cells by microphotometry, imaging or flow cytometry when used with single excitation, green-fluorescent calcium indicators.
