Description
Description: Although Fura-2 has been widely used as the preferred excitation-ratioable calcium indicator it has certain limitations, e.g., lower sensitivity compared to the single wavelength calcium dyes such as Fluo-8® and Cal-520®. AAT has recently developed Fura-8™ to further improve the calcium response of Fura-2. Fura-8 has its emission shifted into longer visible wavelength that is compatible with the common filter sets. It has comparable calcium affinity (to Fura-2). Fura-8™ AM is more sensitive to calcium than Fura-2 AM with higher signal/background ratio than that of Fura-2 AM. We recommend to use Ex/Em = 354/530 nm and 415/530 nm for ratio measurements, i.e., calculating the excitation intensity ratios at 354 nm and 415 nm by monitoring emission intensity at 530 nm.
