通用 PAINT – 动态超分辨率显微镜
超分辨率显微技术在过去十年中彻底革新了生物学研究。这些技术让我们能够以接近蛋白质大小的分辨率观察细胞内的各个组成部分。然而,对活细胞进行成像仍然是大多数超分辨率技术面临的挑战。在这种背景下,uPAINT(纳米尺度拓扑成像通用点积累)技术受到了广泛关注。这种单分子方法通过动态成像活细胞中持续标记的任意膜生物分子,实现了超高分辨率成像,并能追踪单个分子的运动轨迹。

Controlling the TIRF Penetration Depth is Mandatory for Reproducible Results
The main feature of total internal reflection fluorescence (TIRF) microscopy is the employment of an evanescent wave for the excitation of fluorophores instead of using direct light. A property of the…
