Intracellularly abundant sulfane sulfur species including persulfide (R-S-SH), polysulfide (R-S-Sₙ-S-R) and polysulfide (H₂Sₙ) play important roles to maintain intracellular reducing environments. BioTracker Green Sulfane Sulfur Live Cell Dye is a FRET-based fluorescence probe to specifically detect the intracellular sulfane sulfur species. It shows only weak fluorescence without sulfane sulfur, and reversibly fluoresces in response to micromolar concentrations of sulfane sulfur. Its reaction is highly specific and has minimal to no reactivity with H₂S, cysteine residues, and sulfur oxides. The dye is a cell permeable diacetylated form which is hydrolyzed by intracellular esterases to generate a metabolite which is retained within the cells. Thus it is suitable to monitor intracellular concentration of sulfane sulfur via live-cell imaging.Spectral Properties:Absorbance (max): 495nmEmission (max): 525nmResearch Category:Live Cell Dye，官网链接：https://www.sigmaaldrich.cn/product/mm/sct211 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
