The current biosensors based on Förster resonance energy transfer (FRET) lack good anisotrophy-based indicators for detecting rotational changes triggered by analyte-binding. Laskaratou et al. developed a FRET-induced Angular Displacement Evaluation via Dim donor (FADED) tool to expand the existing toolkit. With less bleed-through from a donor with dim fluorescence, the changes in acceptor anisotropy signals of these tools could readily indicate cytosolic calcium dynamics.

调暗供体以照亮基于 FRET 的生物传感器

当前基于 Förster 共振能量转移 (FRET) 的生物传感器缺乏良好的基于​​各向异性的指标来检测由分析物结合引发的旋转变化。拉斯卡拉图等人。通过 Dim 捐助者 (FADED) 工具开发了 FRET 诱导的角位移评估,以扩展现有工具包。由于来自具有暗淡荧光的供体的渗出较少,这些工具的受体各向异性信号的变化可以很容易地表明细胞溶质钙动力学。
