Fura-2 Leakage Resistant AM

Fura-2 leakage resistant AM is a cell-permeable, ratiometric fluorescent calcium indicator. It binds to calcium (Kd = 145 nm) and displays excitation maxima of 340 and 380 nm when calcium-bound or calcium-free, respectively, when the emission is fixed at 505 nm. Fura-2 leakage resistant is also available in a cell-impermeable form (Cay-34994).Formal Name: bis(acetoxymethyl) 2,2'-((2-(5-((acetoxymethoxy)carbonyl)oxazol-2-yl)-5-(2-(2-(bis(2-(acetoxymethoxy)-2-oxoethyl)amino)-5-(3-oxo-3-((prop-1-en-2-yloxy)methoxy)propyl)phenoxy)ethoxy)benzofuran-6-yl)azanediyl)diacetate.
