概述| 货号 | 20415-50ug |
| 描述 | Fura-FF (postassium salt) is a difluorinated analog of the cell-impermeant calcium indicator fura-2 (Item Nos. 19531|20414). Unlike, fura-2, fura-FF has negligible magnesium sensitivity, thus reducing interference from this cation. Fura-FF has a higher calcium dissociation constant than fura-2 (Kd(calcium) = 5.5 and 0.14 µM, respectively). Low affinity calcium dyes, including fura-FF, are preferred for studying compartments with high concentrations of calcium, such as mitochondria, or in cell systems that have relatively low calcium buffering capacities, such as neuronal dendrites and spines.1,2,3 The spectroscopic properties of fura-FF and fura-2 are similar. |
