概述| 货号 | 20414-1mg |
| 描述 | Fura-2 is a pentacarboxylate calcium indicator.1 The spectral properties of fura-2 in the presence of low calcium concentrations (excitation max = 362 nm, emission max = 512 nm) differ from those during high calcium conditions (excitation max = 335 nm, emission max = 505 nm). Measurement of calcium-induced fluorescence at excitation wavelengths of both 340 and 380 nm with a constant emission wavelength of 505 nm allows for calculation of calcium concentrations based on a ratio of the 340/380 values. Employing this ratio method cancels out certain variables that could be considered artifacts when attempting to image calcium concentrations in cells. |
