在过去的二十年里,各种超分辨(SR)显微技术已经发展到突破衍射极限,利用亚衍射激发对荧光发射进行空间调制。光调制荧光蛋白(FPs)可以被特定波长的光激活,产生随机或图案亚衍射激发,从而提高光学分辨率。在本文中,我们关注最近开发photomodulatable FPs或常用的SR显微镜和讨论的概念和策略优化和选择的生物化学和物理性质PMFPs改善老技术的时空分辨率,特别是延时live-cell SR技术。
In the past two decades, various super-resolution (SR) microscopy techniques have been developed to break the diffraction limit using subdiffraction excitation to spatially modulate the fluorescence emission. Photomodulatable fluorescent proteins (FPs) can be activated by light of specific wavelengths to produce either stochastic or patterned subdiffraction excitation, resulting in improved optical resolution. In this review, we focus on the recently developed photomodulatable FPs or commonly used SR microscopies and discuss the concepts and strategies for optimizing and selecting the biochemical and photophysical properties of PMFPs to improve the spatiotemporal resolution of SR techniques, especially time-lapse live-cell SR techniques.
