我们证明了基因编码孔雀石绿(MG)结合氟激活蛋白(FAP)在活细胞刺激发射耗尽纳米显微镜(STED)中的有效性。在活细胞中使用含膜表达FAP或细胞内FAP-肌动蛋白融合的氟化物检测细胞外和细胞内FAP。观察到FWHM为110 ~ 122nm的结构。然而损耗数据表明,给定仪器的分辨率为70纳米。
We demonstrate the effectiveness of a genetically encoded Malachite Green (MG) binding fluorogen activating protein (FAP) for live cell stimulated emission depletion nanoscopy (STED). Both extracellular and intracellular FAPs were tested in living cells using fluorogens with either membrane expressed FAP or as an intracellular FAP-actin fusion. Structures with FWHM of 110-122nm were observed. Depletion data however suggests a resolution of 70nm with the given instrument.
