超分辨率显微镜可实现低于光的经典衍射极限的光学成像,目前空间分辨率高达 20 倍。然而,多目标检测(多重检测)仍然难以实现且耗时。在这里,我们报告了一种基于 DNA 探针快速交换的简单的顺序多重方法,该方法能够利用 (d)STORM、STED 和 SIM 等常见的超分辨率技术进行高效、快速的多重目标检测。我们使用 DNA 折纸纳米结构来分析我们的方法,以定量评估标记、成像和洗涤效率。我们还通过对固定细胞中的多个蛋白质靶标进行成像来证明我们的方法的适用性。许多快乐的回报:我们开发了一种基于 DNA 探针快速交换的简单的顺序多重方法,可以使用 (d)STORM、STED 和 SIM 等常见超分辨率技术实现高效、快速的多重目标检测。
Super-resolution microscopy allows optical imaging below the classical diffraction limit of light with currently up to 20 × higher spatial resolution. However, the detection of multiple targets (multiplexing) is still hard to implement and time-consuming to conduct. Here, we report a straightforward sequential multiplexing approach based on the fast exchange of DNA probes which enables efficient and rapid multiplexed target detection with common super-resolution techniques such as (d)STORM, STED, and SIM. We assay our approach using DNA origami nanostructures to quantitatively assess labeling, imaging, and washing efficiency. We furthermore demonstrate the applicability of our approach by imaging multiple protein targets in fixed cells. Many happy returns: A straightforward sequential multiplexing approach based on the fast exchange of DNA probes has been developed that enables efficient and rapid multiplexed target detection with common super-resolution techniques such as (d)STORM, STED, and SIM.
