FBBBE 是荧光素衍生物,用于检测细胞产生的过氧化氢(H₂O₂)。该探针仅响应胞内过氧化氢,不响应胞外过氧化氢;胞内过氧化氢可将 FBBBE 转化为荧光素,使细胞内荧光信号增强(最大激发 / 发射波长:480 nm / 512 nm)。
实验操作流程
FBBBE 为结晶固体。可选用合适溶剂配制储备液。FBBBE 可溶于 DMSO、二甲基甲酰胺等有机溶剂;上述溶剂建议预先通入惰性气体吹扫除氧。FBBBE 在 DMSO 中溶解度约 25 mg/mL,在二甲基甲酰胺中溶解度约 30 mg/mL。
FBBBE is a derivatized fluorescein compound that is used to detect the production hydrogen peroxide (H₂O₂) by cells. Intracellular H₂O₂, but not extracellular H₂O₂, initiates the conversion of FBBBE to fluorescein, resulting in an increase in intracellular fluorescence (excitation/emission maxima: 480/512 nm).
Laboratory Procedures
FBBBE is supplied as a crystalline solid. A stock solution may be made by dissolving the FBBBE in the solvent of choice. FBBBE is soluble in organic solvents such as DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of FBBBE in these solvents is approximately 25 and 30 mg/ml, respectively.
