We report a probe, LD-FG, for imaging lipid droplet (LD) dynamics by using structure illumination microscopy. LD-FG allows wash-free imaging of LDs, owing to a hydrogen-bond sensitive fluorogenic response. The replacement of photobleached LD-FG with fresh probe molecules from outside the LDs ensures the long-term stability of the imaging. With this buffering fluorogenic probe, fast and unpredictable
我们报告了一种探针LD-FG,用于通过使用结构照明显微镜对脂滴 (LD) 动力学进行成像。由于氢键敏感的荧光反应,LD-FG允许对 LD 进行免洗成像。用来自 LD 外部的新鲜探针分子替换光漂白的LD-FG,确保了成像的长期稳定性。使用这种缓冲荧光探针,可以可视化快速且不可预测的 LD 动态过程。
