Description

Description: Fluo-5N is an analog of Fluo-4 with lower calcium-binding affinity (Kd = ~2.3 uM), making it suitable for detecting intracellular calcium levels in the range of 1 µM to 1 mM that would saturate the response of Fluo-4. Cells may be loaded with Fluo-5N AM ester (#20566) by adding the dissolved indicator directly to dishes containing cultured cells. It is compatible with excitation at 488 nm by argon-ion laser sources, making Fluo-5N useful for confocal microscopy, flow cytometry, and microplate screening applications. It has excitation and emission wavelengths at 494 and 516 nm respectively. Upon calcium binding, its fluorescence intensity increases by >100 fold.
