We demonstrate live-cell STED microscopy of two protein species using photochromic green fluorescent proteins as markers. The reversible photoswitching of two markers is implemented so that they can be discerned with a single excitation and STED wavelength and a single detection channel. Dual-label STED microscopy is shown in living mammalian cells.
我们使用光致变色绿色荧光蛋白作为标记物，展示了两种蛋白质在活细胞中的 STED 显微镜观察。通过可逆光开关实现了两种标记物的切换，使得它们可以在单个激发和 STED 波长以及单个检测通道下被区分开来。双标记 STED 显微镜在活的哺乳动物细胞中得到了应用。
