FRET-PAINT显微镜的最新发展显著提高了DNA-PAINT的成像速度,这是先前报道的无光漂白问题的超分辨率荧光显微镜。本研究通过优化成像速度、DNA探针的解离率、供体信号到受体通道的通血率,试图达到FRET-PAINT的极限速度,并进一步将FRET-PAINT的成像速度提高8倍。COS-7微管的超分辨率成像表明,仅需数十秒即可获得高质量的40纳米分辨率图像。本文的在线版本(10.1186/s13041-018-0414-3)包含补充资料,仅供授权用户使用。
Recent development of FRET-PAINT microscopy significantly improved the imaging speed of DNA-PAINT, the previously reported super-resolution fluorescence microscopy with no photobleaching problem. Here we try to achieve the ultimate speed limit of FRET-PAINT by optimizing the camera speed, dissociation rate of DNA probes, and bleed-through of the donor signal to the acceptor channel, and further increase the imaging speed of FRET-PAINT by 8-fold. Super-resolution imaging of COS-7 microtubules shows that high-quality 40-nm resolution images can be obtained in just tens of seconds.
