| 产品描述 | Fura-2 is a ratiometric fluorescent calcium indicator that can be used to detect calcium in cells. [1] It is a pentacarboxylate that displays excitation maxima of 340 and 380 nm at high and low calcium concentrations, respectively, when the emission is fixed at 510 nm, enabling determination of ratiometric measurements of calcium influx in live cells.
