法國波爾多大學U. Valentin Nägerl和Jean-Baptiste Sibarita等研究人員,開發出一個可用於相關實時單分子成像以及STED顯微鏡的超解析度平臺。相關論文10月21日在線發表於《自然—方法學》雜誌。
研究人員開發了一個超解析度平臺,可以在活細胞中實現相關單分子成像和受激發射損耗螢光顯微術。它可以在生長錐和樹突棘的形態學背景下,以納米級成像顯示突觸蛋白的位置和運動。
據了解,超解析度顯微鏡為揭示活細胞的複雜而動態的結構提供了巨大的機遇。但是,當前的超解析度顯微鏡非常適合揭示蛋白質分布或細胞形態,但不能同時兼顧兩者。

Abstract:
Super-resolution microscopy offers tremendous opportunities to unravel the complex and dynamic architecture of living cells. However, current super-resolution microscopes are well suited for revealing protein distributions or cell morphology, but not both. We present a super-resolution platform that permits correlative single-molecule imaging and stimulated emission depletion microscopy in live cells. It gives nanoscale access to the positions and movements of synaptic proteins within the morphological context of growth cones and dendritic spines.
